mail/spamassassin: Update to 4.0.1 Upstream changes are bugfixes and very minor improvements. Packaging changes are simply changing the version number, patch defuzzing and dropping one fix that is now upstream. Tested on netbsd-9 amd64 for 24h, handling real mail. Take maintainership.

mail/spamassassin: Update to 4.0.0
Tested on NetBSD 9 amd64 with postfix and spamass-milter. NB the rule
renaming below and the modified init.pre, which will not be merged by
updating if init.pre is locally modifed.
Upstream Release Notes:
Introduction
------------
Apache SpamAssassin 4.0.0 contains numerous tweaks and bug fixes over
the past releases. In particular, it includes major changes that
significantly improve the handling of text in international language.
As with any major release, there are countless functional patches and
improvements to upgrade to 4.0.0. Apache SpamAssassin 4.0.0 includes
several years of fixes that significantly improve classification and
performance. It has been thoroughly tested in production systems. We
strongly recommend upgrading as soon as possible.
Notable features:
=================
New plugins
-----------
There are three new plugins added with this release:
#1 Mail::SpamAssassin::Plugin::ExtractText
This plugin uses external tools to extract text from message parts,
and then sets the text as the rendered part. All SpamAssassin rules
that apply to the rendered part will run on the extracted text as
well.
#2 Mail::SpamAssassin::Plugin::DMARC
This plugin checks if emails match DMARC policy after parsing DKIM and
SPF results.
#3 Mail::SpamAssassin::Plugin::DecodeShortURLs
This plugin looks for URLs shortened by a list of URL shortening
services. Upon finding a matching URL, plugin will send a HTTP request
to the shortening service and retrieve the Location-header which
points to the actual shortened URL. It then adds this URL to the list
of URIs extracted by SpamAssassin which can then be accessed by uri
rules and plugins such as URIDNSBL.
Removed plugin
--------------
HashCash module, formerly deprecated, has now been removed completely
Notable changes
---------------
This release includes fixes for the following:
- Support for international text such as UTF-8 rules has been
completed and significantly improved to include native UTF-8
processing
- Bayes plugin has been improved to skip common words aka noise
words written in languages other than English
- OLEVBMacro plugin has been improved in order to detect more
Microsoft Office macros and dangerous content. It has also been
improved to extract URIs from Office documents for automatic
inclusion in rules such as RBL lookups.
- You can now use Captured Tags to use tags “captured” in one rule
inside other rules
- sa-update(1) tool has been improved with three new options:
#1 forcemirror: forces sa-update to use a specific mirror server,
#2 score-multiplier: adjust all scores from update channel by a
given multiplier to quickly level set scores to match your
preferred threshold
#3 score-limit adjusts all scores from update channel over a
specified limit to a new limit
* SSL client certificate support has been improved and made easier to
implement with spamc/spamd
* DKIM plugin can now detect ARC signatures
* More work on improving the configuration and internal coding to use
more inclusive and less divisive language
* spamc(1) speed has been improved when both SSL and compression are
used
* The normalize_charset option is now enabled by default. NOTE: Rules
should not expect specific non-UTF-8 or UTF-8 encoding in the body.
Matching is done against the raw body, which may vary depending on
normalize_charset setting and whether UTF-8 decoding was successful.
* Mail::SPF is now the only supported module used by the SPF plugin.
* Mail::SPF::Query use is deprecated, along with settings
do_not_use_mail_spf, do_not_use_mail_spf_query.
* SPF lookups are not done asynchronously and you may consider using
an SPF filter at the MTA level (pypolicyd-spf / spf-engine / etc)
which generates a Received-SPF header that can be parsed by
SpamAssassin.
* The default sa-update ruleset doesn't make ASN lookups or header
additions anymore. Configure desired methods (asn_use_geodb /
asn_use_dns) and add_header clauses manually, as described in
documentation for the Mail::SpamAssassin::Plugin::ASN.
New configuration options
-------------------------
All rules, functions, command line options and modules that contain
"whitelist" or "blacklist" have been renamed to "welcomelist" and
"blocklist" terms
Old options will continue to work for backwards compatibility until at
least the Apache SpamAssassin version 4.1.0 release
New tflag "nolog" added to hide info coming from rules in SpamAssassin
reports
New dns_options "nov4" and "nov6" added.
IMPORTANT:; You must set nov6 if your DNS resolver is filtering IPv6
AAAA replies.
Razor2 razor_fork option added. It will fork separate Razor2 process
and read in the results later asynchronously, increasing
throughput. When this is used, rule priorities are automatically
adjusted to -100.
Pyzor pyzor_fork option added. It will fork separate Pyzor process and
read in the results later asynchronously, increasing throughput. When
this is used, rule priorities are automatically adjusted to -100
urirhsbl and urirhssub rules now support "notrim" tflag, which forces
querying the full hostname, instead of trimmed domain
report_charset now defaults to UTF-8 which may change the rendering of
SpamAssassin reports
Notable Internal changes
------------------------
Meta rules no longer use priority values, they are evaluated
dynamically when the rules they depend on are finished
DNS and other asynchronous lookups like DCC or Razor2 plugins are now
launched when priority -100 is reached. This allows short circuiting
at lower priority without sending unneeded DNS queries
New internal Mail::SpamAssassin::GeoDB module supporting RelayCountry
and URILocalBL plugins provides a unified interface to Geographic IP
modules. These include:
MaxMind::DB::Reader (GeoIP2)
Geo::IP
IP::Country::DB_File
IP::Country::Fast.
Bayes and TxRep Message-ID tracking now uses a different hashing
method
Optimizations
-------------
Apache SpamAssassin 4.0.0 represents years of work by the project with
numerous improvements, new rule types, and internal native handling of
messages in international languages. These three key optimizations
will improve the efficiency of SpamAssassin:
DNS queries are now done asynchronously for overall speed
improvements
DCC checks can now use dccifd asynchronously for improved throughput
Pyzor and Razor fork use separate processes done asynchronously
for increased throughput
spamassassin: update to use latest rules file and install .asc file again This makes the package break later in 'make install' when it finds out that updates.spamassassin.org does not exist. Bump PKGREVISION.
mail: Replace RMD160 checksums with BLAKE2s checksums All checksums have been double-checked against existing RMD160 and SHA512 hashes The following distfiles were unfetchable (possibly fetched conditionally?): ./mail/qmail/distinfo netqmail-1.05-TAI-leapsecs.patch
mail: Remove SHA1 hashes for distfiles
spamassassin: Update to 3.4.6 upstream: bugfixes
mail/spamassassin: Update to 3.4.5 This is a micro-update carrying a fix for https://cve.mitre.org/cgi-bin/cvename.cgi?name=2020-1946 Upstream changes: In addition to the CVE which shall be announced separately, this release includes fixes for the following: - Improvements to OLEVBMacro and AskDNS plugins - Received and EnvelopeFrom headers matching improvements - userpref SQL schema fixes - rbl and hashbl evaluation improvements - fix for non working TxRep tag names - man page fixes
mail/spamassassin: Update to 3.4.4 This is a micro update (actually 2) with security fixes, and is trivial except for hand-applying some patch hunks that have textual but not semantic conflicts. The upstream announcement hints at minor new features and a new plugin, but does not explain. (There is no NEWS file.)

Log Message:
Update spamassassin to 3.4.2.
From Attila Fueloep in pull request NetBSD/pkgsrc#32.
Apache SpamAssassin 3.4.2 contains numerous tweaks and bug fixes over the
past three and 1/2 years. As we release 3.4.2, we are preparing 4.0.0 which
will move us into a full UTF-8 environment. We expect one final 3.4.3
release.
As with any release there are a number of functional patches, improvements as
well as security reasons to upgrade to 3.4.2. In this case we have over 3
years of issues being resolved at once. And we are laying thr groundwork for
version 4.0 which is is designed to more natively handle UTF-8.
However, there is one specific pressing reason to upgrade. Specifically, we
will stop producing SHA-1 signatures for rule updates. This means that while
we produce rule updates with the focus on them working for any release from
v3.3.2 forward, they will start failing SHA-1 validation for sa-update.
*** If you do not update to 3.4.2, you will be stuck at the last ruleset
with SHA-1 signatures in the near future. ***

Updated to version 3.3.1.
Pkgsrc changes:
- Removed most of the package options; using the options framework for
those choices was not quite correct in the first place. Some have now
fixed values (Perl warnings and taint checks always enabled), some
got converted to variables settable from the make command line, see
options.mk.
- pkglint complained about the variable PLIST_ADD so I renamed it to
DYNAMIC_PLIST.
- SpamAssassin does not come with rules anymore. As a starting point
the official archive of rules at the time of the SA release is
included. At installation time this set of rules gets installed
through the pkgsrc INSTALL file.
- Removed patch-ba and patch-bc, both were integrated upstream.
- Removed patch-be. The quick fix for the bad rule was replaced by
a permanent solution.

Summary of major changes since 3.2.5
====================================
COMPATIBILITY WITH 3.2.5
- rules are no longer distributed with the package, but installed by
sa-update - either automatically fetched from the network (preferably)
or from a tar archive, which is available for downloading separately
(see below, section INSTALLING RULES);
- CPAN module requirements:
- minimum required version of ExtUtils::MakeMaker is 6.17;
- modules now required: Time::HiRes, NetAddr::IP (4.000 or later),
Archive::Tar (1.23 or later), IO::Zlib;
- minimal version of Mail::DKIM is 0.31 (preferred: 0.37 or later);
expect some tests in t/dkim2.t to fail with versions older than 0.36_5;
- no longer used: Mail::DomainKeys, Mail::SPF::Query;
- either Digest::SHA or the older Digest::SHA1 is required, though
note that the DKIM plugin requires Digest::SHA for sha256 hashes
and Razor agents still need Digest::SHA1;
- some IPv6 functionality requires IO::Socket::INET6;
- if keeping the AWL database in SQL, the field awl.ip must be extended to
40 characters. The change is necessary to allow AWL to keep track of IPv6
addresses which may appear in a mail header even on non-IPv6 -enabled host.
While at it, consider also adding a field 'signedby' to the SQL table 'awl'
(and adding 'auto_whitelist_distinguish_signed 1' to local.cf);
see sql/README.awl for details. The change need not be undone even if
downgrading back to 3.2.* for some reason;
- fixing a protocol implementation error regarding a PING command required
bumping up the SPAMC protocol version to 1.5. Spamd retains compatibility
with older spamc clients. Combining new spamc clients with pre-3.3 versions
of a spamd daemon is not supported (but happens to work, except for the
PING and SKIP commands);
- if using one of the plugins (FreeMail, PhishTag, Reuse) which were
previously not part of the official package, please retire your local copy
to avoid it conflicting with a new native plugin;
- as the plugin AWL is no longer loaded by default, to continue using it
the following line is needed in one of the .pre files (e.g. local.pre):
loadplugin Mail::SpamAssassin::Plugin::AWL
- it may be worth mentioning that a rule DKIM_VERIFIED has been renamed
to DKIM_VALID to match its semantics;
- the DKIM plugin is now enabled by default for new installs, if the perl
module Mail::DKIM is installed. However, installation of SpamAssassin
will not overwrite existing .pre configuration files, so to use DKIM when
upgrading from a previous release that did not use DKIM, a directive:
loadplugin Mail::SpamAssassin::Plugin::DKIM
will need to be uncommented in file "v312.pre", or added to some
other .pre file, such as local.pre;
- due to changes in some internal data structures (like Bug 6185, 6254),
some third-party plugins may need to be updated. One such example is
the ClamAVPlugin plugin - please find a fresh version, which can be used
with both SpamAssassin versions 3.2.5 and 3.3.0, on its wiki page at
http://wiki.apache.org/spamassassin/ClamAVPlugin
- versions of amavisd-new between 2.5.2 and 2.6.1 (inclusive) are incompatible
with SpamAssassin 3.3; please upgrade amavisd to 2.6.2 or later, or apply
a workaround https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6257
- support for versions of perl 5.6.* is being gradually revoked
(may still work, but no promises and no support);
- preferred versions of perl are 5.8.8, 5.8.9, and 5.10.1 or later;
- on FreeBSD, please avoid using multithreaded versions of perl older
than 5.10.0 due to small default main thread's stack size, which may
not suffice for some regular expression evaluations;
INSTALLING RULES
Rules are normally installed by running a sa-update command.
The version of sa-update program should match the version of SpamAssassin
modules, so invoking sa-update should be performed only after installing
or upgrading SpamAssassin code, not before.
Installing rules from network is done with a single command,
normally run as root:
sa-update
Installing rules from files:
obtain all the following files:
Mail-SpamAssassin-rules-xxx.tgz
Mail-SpamAssassin-rules-xxx.tgz.asc
Mail-SpamAssassin-rules-xxx.tgz.md5
Mail-SpamAssassin-rules-xxx.tgz.sha1
(where xxx may look something like '3.3.0.r893295')
install rules from a compressed tar archive:
sa-update --install Mail-SpamAssassin-rules-xxx.tgz
(sa-update will need corresponding .asc and .sha1 files with the
same base name in the same directory as the .tgz file)
MAIN NEW FEATURES
- IPv6 support was substantially improved (see below);
- many improvements to the DKIM plugin (understands author domain signatures,
supports multiple signatures, ADSP support with overrides) - (see below);
- added 'if can(Class::method)' conditional statement, allowing configuration
settings to be conditional on plugin capabilities without requiring
new version releases to do so;
- added a --verbose option to the sa-update utility to show updated channels;
- added a configuration option 'time_limit', defaulting to 300 seconds
or whatever the caller (like spamd) provides; attempting to gracefully
terminate the checking when a time limit is reached, reporting the score
and test hits that were collected so far, along with an added hit on
a rule TIME_LIMIT_EXCEEDED;
- more expensive code sections are now instrumented with timing measurements;
timing report is logged as a debug message by the end of processing,
and made available to a caller and to 'add_header' directives through
a TIMING tag;
- added a configuration option skip_uribl_checks to the URIDNSBL plugin,
cross-documented it with skip_rbl_checks;
- preserve order of declared 'add_header' header fields;
- configurable network mask length for the AWL plugin (see below);
- added support for DCC reputations (see below);
- improved error handling and robustness (see below);
- added timestamps when logging on stderr;
- allowed debug areas to be excluded from debugging,
e.g.: -D all,norules,noconfig,nodcc
BUILDING AND PACKAGING
- rules are no longer distributed with the package, but installed by
sa-update
- Makefile.PL has been simplified and a bug fixed in a DESTDIR support
by increasing the minimum required version of ExtUtils::MakeMaker to 6.17
- tools check_whitelist and check_spamd are now included in the distribution,
now called 'sa-awl' and 'sa-check_spamd'
WORKAROUNDS TO PERL BUGS AND LIMITATIONS
- modified the Check.pm plugin to produce smaller chunks of source code
from rules (60 kB) to avoid Perl compiler crashing on exceeding stack size;
- localized global variables $1, $2, etc at several places, avoiding taint
issue from propagating;
- avoided Perl I/O bug by replacing line-by-line reading with read() where
suitable, or played down the EBADF status in other places and only report
it as a dbg instead of a die - while also providing a little speedup
(10 .. 25 %) on reading a message;
- provided a new sub Message::split_into_array_of_short_lines to split
a text into array of paragraph chunks of sizes between 1 kB and 2 kB,
giving less opportunity to runaway regular expressions in rules;
fixes bugs: 5717, 5644, 5795, 5486, 5801, 5041;
MEMORY FOOTPRINT
- as a side-effect of compiling rules in smaller chunks (to avoid compiler
crashes), virtual memory footprint of SpamAssassin is reduced;
- saved some memory by not importing the Pod::Usage unless it is needed;
- saved 350k+ of memory in sa-compile by replacing DynaLoader with XSLoader;
- removed unneeded index from MySQL bayes_token table;
IPv6 SUPPORT
- added IPv6 support for trusted_networks, internal_networks, msa_networks,
whitelist_from_rcvd, and other stuff that uses NetSet and the Received
header field parser, using NetAddr::IP;
- allowed usage of a remote dccifd host through an INET or INET6 socket;
- added IPv6 support to AWL plugin and its utility modules; a network
mask length is now configurable and defaults to /48, which controls
what data is stored in an AWL database;
- sql/README.awl and sql/awl_*.sql: increased suggested awl.ip field width
to 40 characters to be able to hold IPv6 addresses;
- IP_PRIVATE now includes ipv6 variants of private address space,
as well as the ipv6-mapped ipv4 addresses.
- NetSet now understands that ::ffff:192.168.1.2 and 192.168.1.2 are
the same address;
- IPv6 addresses are now properly read from Received header fields;
- when reading Received header fields, the "IPv6:" prefix is stripped from
IPv6 addresses, and "::ffff:" is removed from IPv6-mapped IPv4 addresses
(so strings can match them as simply IPv4 addresses);
- ::1/128 is always included in the trusted_networks/internal_networks set
similar to 127.0.0.0/8;
- some of the IPv6 functionality in SpamAssassin requires that a perl module
IO::Socket::INET6 is available (like accessing a DNS resolver over inet6,
talking to a dccifd host over inet6 socket, SPAMC protocol);
SPAMC
- Mail::SpamAssasin::Client ping may erroneously result in broken pipe;
bump spamc protocol version to 1.5, updated spamd, spamc and Client.pm;
- added -n / --connect-timeout switch to spamc, allowing to separate
a connection timeout from communication timeout;
- added --filter-retries and --filter-retry-sleep;
- increased allowed line length in spamc.conf files to 8 KiB and report
an error when the limit is exceeded;
- fixed issue where spamc would not time out connections to a hung spamd;
- spamc client library leaked the zlib compression buffer if compression
is used;
- spamc long option '--dest' was broken;
SPAMD
- when spamd is started with the daemonize option do not exit the parent
until a child signals that it has logged the pid, to allow a wrapper
script to simply continue immediately after starting spamd;
- additional tempfile cleanup in kill_handler;
- added SPAMD_LOCALHOST option to "make test" to allow specifying
non-127.0.0.1 IP address for use in FreeBSD jail;
API
- adding one optional argument to Mail::SpamAssassin::parse allows caller
to pass additional out-of-band information to SpamAssassin (such as a
deadline time, DKIM verification results, information about a SMTP session,
or dynamic rule hits); this information is made available to plugins and
the rest of the code through a 'suppl_attrib' hash;
- added option 'master_deadline' to the suppl_attrib argument of a
Mail::SpamAssassin::parse method, allowing the caller to override a
time_limit configuration setting;
- Plugin::Check - pick up 'rule_hits' from caller via the new mechanism
and call got_hit() on them;
- simplified adding dynamic score hits and dynamic rules by plugins
(such as AWL, CRM114, FuzzyOcr, Check) by letting got_hit() accept
options tflags and description, and letting it store a supplied
dynamic score for proper reporting;
- let the timing breakdown information be accessible to a caller through
the existing get_tag mechanism (tag TIMING);
- let the generated header fields ('add_header' configuration options)
be accessible to a caller through the existing get_tag mechanism
(tags ADDEDHEADER, ADDEDHEADERHAM, ADDEDHEADERSPAM);
RULES
- rules are no longer distributed with the package;
- new scores were generated by a genetic algorithm (GA) and then manually
tweaked based on cleaned datasets supplied by a dozen volunteers;
- dropped redundant rules or rules causing too many false positives;
- added or updated many rules; incomplete list in no particular order:
vbounce, lotsa_money, muchmoney, image spam, fill_this_form, FreeMail,
European Parliament, HTML attachments, uri_obfu*, urinsrhsbl, urinsrhssub,
urifullnsrhsbl, URI_OBFU_X9_WS, rDNS=localhost, INVALID_DATE_TZ_ABSURD,
RCVD_IN_PSBL, FRT_VALIUM*, BOUNCE_MESSAGE, VBOUNCE_MESSAGE,
__BOUNCE_UNDELIVERABLE, HELO_STATIC_HOST, FILL_THIS_FORM_FRAUD_PHISH,
CHALLENGE_RESPONSE, DKIM_VALID, DKIM_VALID_AU, DKIM_ADSP_*,
NML_ADSP_CUSTOM_{LOW,MED,HIGH}, __VIA_ML, MIME_BASE64_TEXT, LOTTO_URI,
FORGED_MUA_THEBAT_BOUN, FORGED_MUA_THEBAT_CS, UNRESOLVED_TEMPLATE,
__THEBAT_MUA, __ANY_OUTLOOK_MUA, RP_MATCHES_RCVD, one-word X-Mailer,
SPAN rules, skype and misquoted-HTML rules, HTML obfuscation and
Google feedproxy URI rules, advance_fee updates including further
evolved advance fee second-order metarules, test rule for
postmaster+abuse missing, FROM_MISSPACED, fixed FROM_CONTAINS_TAB, a
Facebook redirector pattern, fixed FPs with TVD_SPACE_RATIO regarding
one-word emails and ISO-2022-JP, added exclusion for __ISO_2022_JP_DELIM
to OBFUSCATING_COMMENT, GAPPY_SUBJECT, PLING_QUERY and FM_FRM_RN_L_BRACK
rules, RATWARE_BOUNDARY plus variant, superseded all previous
RATWARE_OUTLOOK stuff, resolved FP in obfuscated URI rule, fixed breakage
in tbird image rule, fixed SUBJECT_FUZZY_MEDS FP on unobfuscated "meds",
added misspaced From header field rule, numeric+cctld URI rule,
updated FH_DATE_PAST_20XX, ...
- added PSBL blacklist - http://psbl.surriel.com/
- added support for http://www.spamhaus.org/css/
- replaces HABEAS, BSP and SSC with RP CERTIFIED;
- use ReturnPath's RNBL, replacing SSBL;
- added rule for plain text attachments with octet-stream MIME type;
- avoided false positives on ISO-2022-JP messages in several rules;
- removed massmailers from uridnsbl_skip_domain in 25_uribl.cf;
- updated various default whitelists, uridnsbl_skip_domain, adsp_override, ...
PLUGINS
- new plugins: FreeMail, PhishTag, Reuse;
- now enabled by default: DKIM;
- now disabled by default: AWL;
- retired plugin: DomainKeys;
AWL PLUGIN
- plugin AWL is now disabled by default;
- added new configuration options auto_whitelist_ipv4_mask_len and
auto_whitelist_ipv6_mask_len to allow more control on what part of
an IP address is stored into an AWL database;
- README.awl: increased a suggested awl.ip field width to 40 characters
to support IPv6 addresses;
- AutoWhitelist.pm: allowed storing a canonicalized IPv6 address, cropped
to a configurable network mask (previously causing SQL server errors:
'value too long');
- let AWL with SQL keep separate records for DKIM-signed and unsigned mail
(when auto_whitelist_distinguish_signed configuration option is true,
and a field awl.signedby exists);
- avoided a race condition in SQLBasedAddrList.pm when multiple processes
try to insert-or-update an awl SQL record: trying INSERT first, and if
that fails go for UPDATE;
- gracefully handle NaN from corrupted database or a broken emulator or
virtualizer;
DCC PLUGIN
- added support for DCC reputations, added setting dcc_rep_percent,
new test check_dcc_reputation_range(), new tag DCCREP
(DCC servers supply reputation data only to licensed clients);
- allowed usage of a remote dccifd host through an INET or INET6 socket;
DKIM PLUGIN
- the DKIM plugin is now enabled by default for new installs if the perl
module Mail::DKIM is installed. However, installing SpamAssassin will
not overwrite existing .pre configuration files, so to use DKIM when
upgrading from a previous release that did not use DKIM, the directive:
loadplugin Mail::SpamAssassin::Plugin::DKIM
will need to be uncommented in file "v312.pre", or added to some
other .pre file, such as local.pre;
- absolute minimal version of Mail::DKIM is 0.31;
support for ADSP requires Mail::DKIM 0.34;
a DNS test (and rule) for NXDOMAIN is operational since Mail::DKIM 0.36_5,
so effectively the recommended version is Mail::DKIM 0.37 or later;
- a perl module Digest::SHA is required if the DKIM plugin is enabled.
If a perl module Digest::SHA is available, the module Digest::SHA1
becomes optional as far as SpamAssassin is concerned, but is still
needed by Razor agents;
- added support for multiple signatures (useful for whitelisting);
- plugin now distinguishes author domain signatures from third party
signatures (useful for whitelisting);
- provides a tag DKIMIDENTITY (in addition to DKIMDOMAIN);
- DKIM now supports Author Domain Signing Practices - ADSP (RFC 5617);
- use the Mail::DKIM::AuthorDomainPolicy instead of Mail::DKIM::DkimPolicy,
when available (since Mail::DKIM 0.34);
- implements an 'adsp_override' configuration directive and adds
an eval:check_dkim_adsp check, which is used by new DKIM_ADSP_* rules;
- rules contain an initial set of 'adsp_override' directives, listing
some of the more popular target domains for phishing (applicable only to
domains which sign all their direct mail with a DKIM or DK signature);
- this plugin can now re-use Mail::DKIM verification results if made
available by a caller, which saves resources and makes it possible
for SpamAssassin to work on a truncated large mail without breaking
DKIM signatures;
- check_dkim_signed and check_dkim_adsp eval rules can now take an optional
list of domain names, which limits their action to listed domains only.
It facilitates building DKIM-based rules for specific domains, without
having to resort to meta rules;
- draft-ietf-dkim-ssp-10/RFC-5617 made Author Domain Signature based on 'd':
updated ADSP code accordingly; changed whitelisting code to be based on
SDID ('d') instead of AUID ('i');
- Plugin/DKIM.pm: terminology changes in comments and logging according
to RFC 5617 and draft-ietf-dkim-rfc4871-errata-07;
BUG FIXES
- fixed Rule2XSBody segfaults;
- no longer treat user data as perl booleans (a string "0" is a false);
- avoid data from the wild be interpreted as perl regular expressions;
- ArchiveIterator: prevent _scan_directory from passing directories
to _scan_file (on NFS it would fail with EISDIR on read(2);
- fixed inserting the SpamAssassin -generated header fields after a
multiline Return-Path header field;
- fixed vpopmail support;
- fixed incorrect mode bits when creating lock files for AWL;
- fixed some cases where :addr headers were parsed incorrectly;
- fixed leakage of 'whitelist_from_rcvd' entries between spamd users;
- fixing run_and_catch, which failed to catch a non-timed run;
- 127/8 isn't an illegal IP;
- reworked the M::S::Timeout module to deal with nested timers as one would
expect: an inner timer shouldn't be able to extend an outer timer's limit;
account for time elapsed in the submitted subroutine when restarting an
outer timer; reset() should have accounted for time already spent;
deal with nested timed runs where alarm(0) does not provide remaining time;
- the 'exists:' evaluator in HEADER rules now works as documented
and tests for existence of a header field, instead of testing for
a header field body being nonempty; internally, the pms->get can
also now distinguish between empty and nonexistent header fields;
- applied fixes to header fields parsing in several places: header field
names are case-insensitive, whitespace is not required after a colon,
obsolete rfc822 syntax allowed whitespace before a colon;
VBounce: match "Received:" only at the beginning of a line;
- fixed bugs 6237 and 6295: 1.0.0.0/8 and 2.0.0.0/8 are now valid allocated
address ranges, fixed a corresponding rule RCVD_ILLEGAL_IP;
- fixed bug 6205 comment 5 in URIDetail.pm;
- 'pyzor_options' in Plugin/Pyzor.pm was not untainted;
- made the URIDetail plugin taint safe;
- fixed parsing of multi-line Received header fields for
BOUNCE_MESSAGE/VBOUNCE_MESSAGE et al;
- Bug 6206, Bug 2536: spamd: untaint directory as obtained from a password
file or from vpopmail utilities, avoid implicit untainting; report error
if user preferences file exists but cannot be accessed;
- avoided using raw data from DNS as a regexp in Plugin/ASN.pm;
- ensured the dbg() and info() calls always return the same value (true)
regardless of log level;
- suppressed logging of $& when its value is not available (i.e. when
no regexp has been evaluated during rule evaluation);
- Exporter never really worked in SA, was not enclosed in BEGIN {};
- masses/runGA and masses/mk-baseline-results: prevent a shell 'source'
command from loading an unrelated file named 'config' which happens to be
in the current PATH - must use a ./ in an arg to a 'source' command;
ERROR HANDLING, ROBUSTNESS
- improved error detection and reporting: test status of all system calls
and I/O operations (or explicitly document where not), and report
unexpected failures;
- eval calls now check for eval result instead of testing the $@, which
is not always reliable;
- localized $@ and $! in DESTROY methods to prevent potential calls to eval
and calls to system routines in code executed from a DESTROY method
from clobbering global variables $@ and $!;
- Util::helper_app_pipe_open_unix: contain a failing exec with an eval
to prevent additional cases of process cloning. The exec could fail
this way when given tainted arguments;
- Util::helper_app_pipe_open_unix: flush stdout and stderr before forking,
otherwise an error reported by exec (such as 'insecure dependency')
was lost in a buffer;
- eval-protected an open($fh,'-|') to capture implied fork failures
due to lack of system resource;
- explicit untainting: combine "use re 'taint'" with untaint_var(),
avoiding implicit perl untainting, along with workarounds to prevent it;
- added 'use strict' where missing;
- avoided a bunch of warnings on "Use of uninitialized value";
- clearly report reasons for helper application process failures;
- t/SATest.pm: provide information about the process failure reason
if a system() call fails; improved its reporting of failures;
- improved error reporting in Plugin/DCC.pm on finding a DCC home directory
to facilitate troubleshooting;
OTHER CHANGES
- pseudoheader "ALL:raw" returns a pristine header section,
and pseudoheader "ALL" returns a cleaned header section
- total rewrite of URI detection in plain text body;
- many updates to the list of top level domains;
- added 'util_rb_3tld', allowing 3-level TLDs to be listed in URIBLs and
allowing new 3TLDs to be added from rule updates;
- avoided trusted_networks bog down due to O(n^2) loop with millions
of entries;
- applied fixes to Plugin/VBounce.pm, updated VBounce ruleset;
- added support for a 'Communigate Pro' Received header field;
- parse Communigate Pro "with HTTPU" auth token;
- let DependencyInfo.pm understand a concept of recommended module version,
besides a required version;
- provided a workaround for Net::DNS::Packet::new inconsistency;
- let SpamAssassin use either Digest::SHA or Digest::SHA1, whichever is
available (the Digest::SHA is now a base module since perl 5.10.0);
- improved parsing of eval-type rules: allow unquoted domain names as
arguments, disallow unmatched quotes;
- provided a new module Mail::SpamAssassin::BayesStore::BDB. It should be
treated as alpha-quality (needs more testing) and is not yet ready for
production use;
- exposed existing function 'received_within_months' as an eval function
in Plugin/HeaderEval.pm;
- moved rc script to /var/lock/subsys/spamd instead of
/var/lock/subsys/spamassassin so 'service spamd status' will work;
- added feature to re-download MIRRRORED.BY files at least once a week, or if
'sa-update --refreshmirrors' switch is used;
- input delimiter $/ can be corrupted by a plugin, localize $/ and $\ before
calling a plugin;
- bumped the retry counter to 180 seconds for starting spamd on slow machines;
- resolved Bug 5325: syslog severity level in spamc/libspamc.c for max
message size (changed LOG_ERR into LOG_NOTICE for the message:
"skipped message, greater than max message size");
- added checker to avoid taint warnings if hostname is returned as '(none)';
- altered sa-update to produce an error message if a channel doesn't exist;
- Bug 6150, Bug 6127, Bug 5981, Bug 5950, Bug 6191: let spamd log/report
a child process exit status or aborting condition in an informative way;
- added checker to detect accidental match-everything regexps in rules;
- updated garescorer for 3.3.0: use more epochs in GA runs for better scores;
clarify some mass-check warning output, ensure rule name always appears at
start of line; if a rule had no default/existing score in 50_scores.cf,
don't tell the GA that 1.0 is an appropriate default value, instead pick
the midway point of its score range. this produces better results;
remove some dead code from masses/score-ranges-from-freqs;
- set garescorer.c to report performance as iterations per second;
- added test to ensure that all config settings are correctly handled when
switching between users; added more config setting type metadata to enable
those tests to work; and fix URIDetail to store config on the {conf} object,
not on the plugin;
- moved 'release tests' to xt/ directory; mirror long-running, net-tests and
stress tests with xt/50_testname.t scripts to enforce their run before a
release;
- made numerous additional and updated self-tests;
- added a Test::Perl::Critic release-test;
- cleaned up some code based on suggestions by perl module Test::Perl::Critic,
among others:
. enable TestingAndDebugging::ProhibitNoStrict test but allow the
use of 'no strict "refs"';
. deal with BuiltinFunctions::RequireGlobFunction;
. deal with ControlStructures::ProhibitMutatingListFunctions
removing this exception from xt/60_perlcritic.t;
. deal with BayesStore/BDB.pm, Variables::ProhibitConditionalDeclarations
. now that the module Time::HiRes is a required module, we can afford
to replace a select() with Time::HiRes::sleep, and remove exception
BuiltinFunctions::ProhibitSleepViaSelect from xt/60_perlcritic.t;
- updated documentation, fixing numerous typos and mistakes in documentation
text and in log messages;
- extensively improved development process:
. automated testing through Hudson, a continuous integration tool;
. improved mass-check system and rules oversight;
Added fix for bad rule FH_DATE_PAST_20XX, triggering for every message since 2010-01-01. Ok by agc@.
Starting with ExtUtils::MakeMaker 6.43 some public variables (esp. Recognized_Att_Keys) were made private, which broke SpamAssassin's (ab)use of those variables. For details see https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6131. Perl 5.10.1 includes ExtUtils::MakeMaker 6.55_2 and consequently building SpamAssassin 3.2.5 with DESTDIR support in pkgsrc does not work anymore. The fix changes the decision whether the used EU::MM module has good enough DESTDIR support to depend only on the version number (ie. mm_has_good_destdir is true) instead of the availability of the key 'DESTDIR' in the (now non-public) Recognized_Att_Keys hash. Ok to commit during freeze by wiz@
Updated to version 3.2.5. Pkgsrc changes: - p5-DB_File is now required on all systems, even those where Perl already detects the native db-functions (dbopen,...) and thus provides DB_File. This should prevent subtle errors like the one in PR pkg/37751 at the price of installing an additional package. - Added explanation to patch-ay. - patch-bc was adapted to the changes for the path of compiled rulesets. - patch-bd is no longer necessary, the public key is now cross-verified. - shut up some warnings from pkglint regarding "set -e" and quoted variables. Changes since version 3.2.4: ============================ 3.2.5 is a minor bug-fix release. Summary of changes: - bug 5775: newer gpg versions require keys to be cross-certified (backsig). Did a cross-verify on our sa-update public key and re-exported. (If you are already seeing "GPG validation failed" errors from sa-update, see http://wiki.apache.org/spamassassin/SaUpdateKeyNotCrossCertified .) - bug 5899: add perl version string to the storage area for compiled rulesets, to avoid crashes when perl is upgraded between major versions (e.g perl 5.8.x to 5.10.0) and the ABI breaks - bug 5496, bug 5910: clear some FORGED_MUA_OUTLOOK false positives, particularly on the new-format Message-ID generated by the Outlook Express version used in Windows XP service pack 3 - bug 5730: when using Postgres >= 8.1.0 with Bayes, this error occurs: 'WARNING: nonstandard use of \ in a string literal at character'. fix, thanks to Tomasz Ostrowski - bug 5769: fix 'sa-compile: eval failed: Can't find label NO' error, caused in rare circumstances when sa-compile attempted to deal with rules written using 'replace_rules' features - bug 5858: fix circular reference memory leak caused by some messages - bug 5815: update 2TLD list to include .rs CCTLD - bug 4706: remove HG_HORMOME rules due to poor performance - bug 5835: typo in POD docs for SPF plugin; thanks to Benny Pedersen for fix - bug 5839: a missing or failed eval rule function could mistakenly count as a rule hit, fixed - trivial bugfix for the VBounce ruleset: __BOUNCE_FROM_DAEMON incorrectly used + instead of *, so some From addresses were not being recognised as bounce senders
Update sa-update PGP key to fix GnuGP 1.4.9 "cross-certified" error (see http://wiki.apache.org/spamassassin/SaUpdateKeyNotCrossCertified). Bump PKGREVISION. Ok with pkgsrc-security.
Updated to version 3.2.4.
Pkgsrc changes:
- Due to "user-destdir" mode not working yet switched to "destdir" mode
for the time being.
- Explicitly listed licence information.
- Listed submitted bug identifiers for patch-ba and patch-bc.
Changes since version 3.2.3:
============================
3.2.4 is a major bug-fix release, with a few minor new features. Summary of
changes:

disappeared without warning
- bug 5715: allow for more than one sa-update MIRRORED.BY file host in DNS,
for redundancy

"check_dkim_valid" (an alias for a "check_dkim_verified" misnomer); new
tags _DKIMIDENTITY_ and _DKIMDOMAIN_; updated terminology; verification
speedup with Mail::DKIM 0.30 (or its pre-releases)
- bug 5696: sa-compile: cut regexp base strings at Unicode high codepoints,
to avoid corruption of patterns containing UTF-8
- bug 5637: bayes_file_mode is handled incorrectly when creating bayes.mutex,
resulting in incorrect permissions on that file; fix by Mihaly Barasz

named '__db.{filename}' are present; work around. thanks to J. Nick
Koston for the report and fix
- bug 5606: too-early init_learner() call causes root's user prefs file to
be read when spamd is started; this is inappropriate. fix
- bug 4179: if allow_user_rules is 1, user rules are not unique to each
user; one user's user rules can appear in later scans for other users

'username' but does not read user_prefs files from anywhere
- bug 5665: spamd may fail to notice that a child has completed exiting,
and keeps in the child list in state 'K', eventually filling up the
child list with 'ghost' children. fix

due to no hits
- bug 5681: look up IP addresses found in 'X-Yahoo-Post-IP' and
'X-SenderIP' headers, too, thanks to Martin Blapp
- Bug 5589: Refined async events handling and DNS lookup completions
- bug 5586: RDNS_NONE has false positives if the MTA doesn't put the hostname
in the Received header, like Communigate Pro. add an exception for this
- bug 5748: fix locale problem with use of external sort in sa-compile
Updated to version 3.2.3.
Pkgsrc changes:
- Added security/gnupg as a required package. Without it, sa-update does not
work.
- Added requirement for p5-INET6 which may be needed for IPv6 nameservers.
Until now, this only worked because p5-Net-DNS already pulled in this
package.
- New option "inet6" (enabled by default) for switching off the requirement
for p5-INET6.
- Got rid of some backslashes in options.mk
- patch-ba and patch-bc correct discrepancies between the man page
and the code. Additionally, they adapt hard-coded paths to the actual
installation. Submitted upstream.
Relevant changes since version 3.2.1:
=====================================
3.2.3 is a major bug-fix release. Summary of changes:
- bug 5574: fix new setuid code to work with perl 5.6.1, and to support DCC and
Pyzor in all releases of perl
- bug 5107: change default 'user_scores_ldap_username' to be the null string,
allowing anonymous binding; fix 'schema' syntax error in LDAP config support
- zeroing an 'eval' rule's score did not stop it running. fix, thanks to
Richard Birkett <richard+spamassassin at musicbox.net>
- bug 5571: allow for new message ID format we have seen from Vista or Windows
2003 Server MAPI to avoid false positives
- bug 5397: RDNS_DYNAMIC should never fire on a PTR with 'static' in it; thanks
to Martin Blapp <mbr at freebsd.org>. bug 5563: RDNS_DYNAMIC rules use
order-dependent fields where it is unsafe to depend on this, fix. bug 5564:
__RDNS_DYNAMIC_IPADDR does not hit all of its test patterns, fix.
- bug 5475: fix FORGED_MUA_AOL_FROM to allow <*@{aol,cs}.*> addresses instead
of just <*@{aol,cs}.com>
3.2.2 is a minor bug-fix release. Summary of changes:
- bug 5548: Certain mail input can take a long time to scan with 100% CPU
utilisation, due to backtracking in a rule's regexp. fix
- bugs 5510, 5518, 5529: fix 'make test' when running as root, needed for CPAN
- bug 5419: kill -HUP of pidof spamd causes the ps name to change from spamd
to perl. fixed
- bug 5535: 'make test' errors in Windows caused by nonportable use of
getpwuid
- bug 5462: multiple DNS records for a host name should allow use of spamd -H
for load balancing installs to work
- bugs 5509, 5511: fix network lookup timeouts, where lookups were being lost
once a timeout was hit; also fix code to match documentation on
rbl_timeout's scaling and minimum duration of 1 second; and attempt to
collect already-received DNS responses when the timeout is reached; improve
related debugging output. Thanks to Mark Martinec
- bugs 5412, 5478, 5522: Fix problems using the spamc -x option with certain
other options; 'spamc -x -R' always returned 0, instead of the exit code, on
error. Bug 5478: in addition, 'spamc -x -e /command' would still run the
command, even if errors meant that the filtered text would be unavailable,
which contradicted -x.
- bug 5445: body eval tests defined in user_rules cause ugly 'Subroutine

security update for spamassassin
- pkgsrc/mail/spamassassin/Makefile patch
- pkgsrc/mail/spamassassin/distinfo patch
Update to SpamAssassin 3.1.9 to fix a denial of service vulnerability. The
package has been updated to SpamAssassin 3.2.1 on pkgsrc-HEAD but this major
new version will not be pulled up to the stable branch.
Changes in Spamassassin 3.1.9:
- bug 5480: fix for CVE-2007-2873: a local user symlink-attack DoS
vulnerability. It only affects systems where spamd is run as root, is used
with vpopmail or virtual users via the "-v"/"--vpopmail" OR
"--virtual-config-dir" switch, AND with the "-x"/"--no-user-config AND
WITHOUT the "-u"/"--username" switch AND with the "-l"/"--allow-tell"
switch. This is not default on any distro package, and is not a common
configuration. More details of the vulnerability can be read at
<http://spamassassin.apache.org/advisories/cve-2007-2873.txt>.
- bug 5353 - meta rule parsing should handle not equal ("!=") syntax.
- set the score for URI_TRUNCATED to 0.001.
- bug 5337: change the start order for Fedora such that spamd starts before
the MTA.
Updated to version 3.2.1. Pkgsrc changes: - Added some comments to patch files. - Adapting patch-aq to changes in the README file. - Added forgotten direct requirement for p5-Compress-Zlib. - Since 3.2.0 at least version 3.43 of p5-HTML-Parser is needed. - Installation to DESTDIR is possible as root. - Substituted correct paths in spamc.pod (source file for spamc.1). - Added VARBASE to BUILD_DEFS to silence pkglint warnings. Changes since version 3.2.0: ============================ 3.2.1 is a major bug-fix release, including a potential local DoS. The major highlights are: - bug 5480: fix for CVE-2007-2873: a local user symlink-attack DoS vulnerability. It only affects systems where spamd is run as root, is used with vpopmail or virtual users via the "-v"/"--vpopmail" OR "--virtual-config-dir" switch, AND with the "-x"/"--no-user-config AND WITHOUT the "-u"/"--username" switch AND with the "-l"/"--allow-tell" switch. This is not default on any distro package, and is not a common configuration. More details of the vulnerability can be read at <http://spamassassin.apache.org/advisories/cve-2007-2873.txt>. - bug 5488: zero some rules causing false positives: FH_HOST_EQ_D_D_D_DB and FH_HOST_EQ_D_D_D_D. - bug 5257: re-raise autolearn ham threshold to 1.0; the lower value used in 3.2.0 was creating problems. - bug 5422: in spamd, deleting hash entries from the SIGCHLD signal handler is unsafe, causes corruption of the data structure, and results in 'prefork: ordered child N to accept, but they reported state '1', killing rogue' errors. fix. - bug 5102: tighten up regexp for FORGED_HOTMAIL_RCVD to avoid some FPs. - bug 5457: spamc build and test should handle not having zlib available. - bug 5379: spamd could crash at startup if its preloading temporary directory already exists. fix. - bug 4616: spamc config can cause command line options to be ignored. fix. - bug 5485: zero score DK/DKIM_POLICY_SIGNSOME rules since they'll always fire due to defaults (unless there's an explicit SIGNALL policy). - bug 5492: VBounce rule was looking in header instead of body for whitelisted relays. fix. - bug 5487: prevent multiple "urirhssub"s using the same zone from overwriting each other. - bug 5432 - Change default in Win32 build to not build spamc. - bug 5446: add --updatedir option to sa-compile and remove inaccurate re2c required version info from pod. - bug 5436: add omitted "ifplugin" statements to the configuration, which would otherwise cause lint errors if the default plugins were disabled. - bug 5477: prevent Rule2XSBody info message from appearing on stderr during spamd startup.
Updated to version 3.2.0.
Pkgsrc changes:
- Removed PKG_DESTDIR_SUPPORT until the issue with encoded ownership in
+INSTALL files is resolved.
- made pkglint shut up about some warnings (CONFIGURE_DIRS, BUILD_DIRS,
hidden commands with @)
- parse-rules-for-masses has moved in the source archive.
- The directories "masses" and "tools" are no longer distributed in the
archive so I simplified the post-install target.
- Since "tools" is gone, the post-extract: target is obsolete.
- MESSAGE now points at sa-compile.
- Spamc depends on zlib now, so we needed the appropriate buildlink3 file.
Summary of changes since version 3.1.8:
=======================================
* new behavior for trusted_networks/internal_networks: the 127.* network
is now always considered trusted and internal, regardless of configuration.
* bug 3109: short-circuiting of 'definite ham' or 'definite spam' messages
based on individual short-circuit rules using the 'shortcircuit' setting,
by Dallas Engelken <dallase /at/ uribl.com>.
* bug 5305: implement 'msa_networks', for ISPs to specify their Mail
Submission Agents, and extend network trust accordingly.
* bug 4636: Add support for charset normalization, so rules can be written
in UTF-8 to match text in other charsets.
* sa-compile: compilation of SpamAssassin rules into a fast parallel-matching
DFA, implemented in native code.
* "tflags multiple": allow writing of rules that count multiple hits in a
single message.
* bug 4363: if a message uses CRLF for line endings, we should use it as
well, otherwise stay with LF as usual; important for Windows users.
* bug 4515: content preview was omitting first paragraph when no Subject:
header was present.
* The third-party modules used by sa-update are now required by the
SpamAssassin package, instead of being optional.
* Bug 5165: 'sa-update --checkonly' added to check for updates without
applying them; thanks to <anomie /at/ users.sourceforge.net>
* Bugs 4606, 4609: Adjust MIME parsing limits for nested multipart/* and
message/rfc822 MIME parts.
* bug 5295: add 'whitelist_auth', to whitelist addresses that send mail
using sender-authorization systems like SPF, Domain Keys, and DKIM
* Removed dependency on Text::Wrap CPAN module.
* Received header parsing updates/fixes/additions.
Spamc / spamd:
* bug 4603: Mail::SpamAssassin::Spamd::Apache2 -- mod_perl2 module,
implementing spamd as a mod_perl module, contributed as a Google Summer of
Code project by Radoslaw Zielinski.
* bug 3991: spamd can now listen on UNIX domain, TCP, and SSL sockets
simultaneously. Command-line semantics extended slightly, although fully
backwards compatibly; add the --ssl-port switch to allow TCP and SSL
listening at the same time.
* bug 3466: do Bayes expiration, if required, after results have been
passed back to the client from spamd; this helps avoid client timeouts.
* more complete IPv6 support.
* spamc: Add '-K' switch, to ping spamd.
* spamc: add '-z' switch, which compresses mails to be scanned using
zlib compression; very useful for long-distance use of spamc over the
internet.
* bug 5296: spamc '--headers' switch, which scans messages and transmits
back just rewritten headers. This is more bandwidth-efficient than the
normal mode of scanning, but only works for 'report_safe 0'.
* Bump spamd's protocol version to 1.4, to reflect new HEADERS verb used
for '--headers'.
Mail::SpamAssassin modules and API:
* bug 4589: allow M::SA::Message to use IO::File objects to read in
message (same as GLOB).
* bug 4517: rule instrumentation plugin hooks, to measure performance,
from John Gardiner Myers <jgmyers /at/ proofpoint.com>.
* add two features to core rule-parsing code; 1. optional behaviour to
recurse through subdirs looking for .cf/.pre's, to support rules compilers
working on rulesrc dir. 2. call back into invoking code on lint failure,
so rule compiler can detect which rules exactly fail the lint check.
* bug 5206: detect duplicate rules, and silently merge them internally
for greater efficiency.
* bug 5243: add Plugin::register_method_priority() API, allowing plugins
to control the relative ordering of plugin callbacks relative to other
plugins' implementations.
* Reduced memory footprint.
Plugins:
* bug 5236: Support Mail::SPF replacement for Mail::SPF::Query.
* bug 5127: allow mimeheader :raw rules to match newlines and folded-header
whitespace in MIME header strings.
* bug 4770: add ASN.pm plugin, contributed by Matthias Leisi <matthias at
leisi.net>
* bug 5271: move ImageInfo ruleset into 3.2.0 core rules, thanks to
Dallas Engelken <dallase /at/ uribl.com>.
* VBounce ruleset and plugin: detect spurious bounce messages sent by
broken mail systems in response to spam or viruses. (Based on Tim
Jackson's "bogus-virus-warnings.cf" ruleset.)
* DomainKeys/DKIM: Mail::DKIM is now preferred over Mail::DomainKeys,
since the latter module is no longer actively maintained, and Mail::DKIM
can handle both DomainKeys and DKIM signatures.
* DKIM: separate signature verification from fetching a policy: can save
a DNS lookup for each unverified message by setting score to 0 for all
policy-related rules (DKIM_POLICY_SIGNALL, DKIM_POLICY_SIGNSOME, and
DKIM_POLICY_TESTING). (thanks to Mark Martinec)
* DKIM: support testing flags in the public key, as well as in the policy
record. (thanks to Mark Martinec)
* DKIM: skip fetching a policy (SSP) if a signature does verify, according
to draft-allman-dkim-ssp-02 (thanks to Mark Martinec)
* Move rule functionality and checking into separate Check plugin, allowing
third parties to implement alternative scanner core algorithms.
* core EvalTests code moved into various plugins.
* Plus lots of miscellaneous bug fixes.

rewrites as well
- bug 4748: add ExpressionEngine and Google redirector patterns
- bug 3815: add _RELAYCOUNTRY_ tag so that the RelayCountry plugin can
put in the list of countries relayed through
- bug 4090: x86_64 platforms (linux specifically) have an issue compiling
libspamc.so causing RPM build failures
- bug 4791: fix issue where perl would throw a UTF-8 warning for certain
messages
- bugs 4606, 4609: Adjust MIME parsing limits
- bug 4780: fix IP_ADDRESS & LOCALHOST regexes to correctly parse IPv6
addresses
- bug 4728: DUL rules should only use the last external IP, not all but
the first of the external IPs
- bug 4700: certain privileged configuration settings can inject code,
due to a bad fix for bug 3846. Back that out
Removed patch-ar again, as I have found a way to exploit it. Bumped PKGREVISION.
Added patch-ar, which fixes a Perl error in tainted mode. Removed the checksum of the non-existant patch-ax from distinfo.

pkgsrc guide.
- Removed patch-ax again; it is already incorporated in 3.1.0.
- Reworked DESCR to use less than 25 lines.
- Removed SPAMASSASSIN_VERSION for clarity of DISTNAME and PKGNAME.
- Prepended variables internal to the package with an underscore.
- Rearranged MAKE_PARAMS alphabetically.
- Simplified some internal variables (concatenation instead of
substitution: _EGDIR, _DOCDIR,...)
- Loop variables use all lower-case now.
- Added a rule to lower score for mail from pkgsrc-bugs in netbsd_lists.cf.
- The test t/spf.t (fails for SPF_HELO_*) has a know problem (SA Bug 4685).
Relevant changes since version 3.0.4:
=====================================
- Apache preforking algorithm adopted; number of spamd child processes is now
scaled, according to demand. This provides better VM behaviour when not
under peak load.
- Inclusion of sa-update script which will allow for updates of rules and
scores in between code releases.
- added PostgreSQL, MySQL 4.1+, and local SDBM file Bayes storage modules. SQL
storage is now recommended for Bayes, instead of DB_File. NDBM_File support
has been dropped due to a major bug in that module.
- detect legitimate SMTP AUTH submission, to avoid false positives on
Dynablock-style rules.
- new Advance Fee Fraud (419 scam) rules.
- removed use of the Storable module, due to several reported hangs on SMP
Linux machines.
- Converted several rule/engine components into Plugins such as:
AccessDB, AWL, Pyzor, Razor2, DCC, Bayes AutoLearn Determination, etc.
- new plugins: DomainKeys (off by default), MIMEHeader: a new plugin to perform
tests against header in internal MIME structure, ReplaceTags: plugin by Felix
Bauer to support fuzzy text matching, WhiteListSubject: plugin added to
support user whitelists by Subject header.
- TextCat language guesser moved to a plugin. (This means "ok_languages"
is no longer part of the core engine by default.)
- Razor: disable Razor2 support by default per our policy, since the
service is not free for non-personal use. It's trivial to reenable.
- DCC: disable DCC for similar reasons, due to new license terms.
- Net::DNS bug: high load caused answer packets to be mixed up and delivered as
answers to the wrong request, causing false positives. worked around.
- DNSBL lookups and other DNS operations are now more efficient, by using a
custom single-socket event-based model instead of Net::DNS.
- add support for accreditation services, including Habeas v2.
- better URI parsing -- many evasion tricks now caught.
- URIBL lookups are prioritized based on the location in the message
the URI was found.
- mass-check now supports reusing realtime DNSBL hit results, and sample-based
Bayes autolearning emulation, to reduce complexity.
- sa-learn, spamassassin and mass-check now have optional progress bars.
- modify header ordering for DomainKeys compatibility, by placing markup
headers at the top of the message instead at the bottom of the list.
- spamd/spamc now support remote Bayes training, and reporting spam.
- spamc now supports reading its flags from a configuration file using the -F
switch, contributed by John Madden.
- added SPF-based whitelisting.
- Polish rules contributed by Radoslaw Stachowiak.
- many rule changes and additions.
Added a patch to fix a potential DoS vulnerability (CVE-2005-3351). See http://issues.apache.org/SpamAssassin/show_bug.cgi?id=4570 http://secunia.com/advisories/17386
Update to version 3.0.4. This solves the update request in PR pkg/30452. No pkgsrc related changes. This release fixes a recently reported DoS vulnerability. Highlights of the release ------------------------- - Certain invalid "Content-Type" headers would cause SpamAssassin to incorrectly process parts of the message. - Certain long message headers could cause slowness when parsing the message. - Added in SURBL JP list. - URI anti-obfuscation updates. - Additional bug fixes.
Updated to version 3.0.3. Merged the two rules in netbsd_lists.cf into one because problem reports mostly do not contain "x-send-pr" anymore. Disabled installation of netbsd_lists.cf in PKGSYSCONFDIR (it is still included in the "examples" directory). Changes since 3.0.2 =================== - Fixed possible memory bloat from large AutoWhitelist db files - Fixed where user defined rules scores became ignored - Updated parsing code for several Received: header formats - Increased some BAYES_* scores for the network+bayes score set - Document set_tag for Plugin API and added get_tag - Additional bug fixes.
Add RMD160 digests.
After changing the SUBST-stage to 'pre-configure' for 3.0.2, Makefile.PL was changed after perl5-configure had been run and the Makefile created. For some people, this resulted in a message Makefile out-of-date with respect to Makefile.PL at the build stage. Omitting the first substitution (sa1) and the corresponding part of patch-ab solved this. This patch had been unnecessary for some time anyway. This should resolve pkg/29255.
Update to 3.0.2. From the changelog:
This release detects legitimate SMTP AUTH submission, to avoid
false positives on Dynablock-style rules. The URIDNSBL plugin has
been fixed to honor the uridnsbl_max_domains config option. Various
documentation and rule fixes. The ability to deal with 'rewrite_header
Subject' markup when no Subject header exists. 'make test' failure
on Solaris has been fixed.
pkgsrc changes:
* Use subst.mk in pre-configure, rather than post-patch, for easier
regeneration of patches.
OK'd by heinz@.
Update to 3.0.1. This is a minor maintenance release to 3.0.0 and the old archive was no longer available on the primary sites.
Update to version 3.0.0. Tested on NetBSD 1.6.2, Solaris 9 and Debian 3.0. Important changes since 2.64 (for details see the file 'Changes') - support for sender authentication using the Sender Policy Framework (SPF) - checking for web links of known spam advertisers (SURBL) - modular plugin architecture - improved SQL database support for storing user data in server installations - improved email classification - SpamAssassin is now part of the Apache Foundation
Update to 2.64.
This also includes the fix for PR pkg/26386 (problems with
PKG_CONFIG=no).
Summary of major changes since 2.63
-----------------------------------
- Security fix prevents a denial of service attack open to certain
malformed messages; this DoS affects all SpamAssassin 2.5x
and 2.6x versions to date.
- Backported several very reliable rules from the SpamAssassin 3.0.0
codebase.
Correct bad substitution of @PREFIX@ in spamd.raw
Update to 2.63. Tested on NetBSD and Solaris 8.
Summary of major changes since 2.62
-----------------------------------
- Fixed bug related to perl 5.005 which stopped SpamAssassin from being
runnable
- Fixed bug where "spamassassin -l" parameter wouldn't be untainted before
being used
- Added caching of body rendering results so that the message wouldn't
be rendered the same way multiple times unnecessarily.
Summary of major changes since 2.61
-----------------------------------
- Fixed two bugs related to Received line generation and parsing.
- Modified two rules to reduce false positives.
- Fixed bug where spamd temporary init directory wasn't removed in some
situations.
- Modified HABEAS_SWE to function even if the Habeas headers were out of
their normal order.
- Fixed bug where reporting wouldn't remove message markup before being
learned by Bayes.
- Fixed bug where report_safe_copy_headers would reverse the order of the
Received headers.
- Fixed several bugs in the Bayes system caused by DB_File oddities.
Update to version 2.61
Summary of major changes since 2.60
-----------------------------------
- Dramatically reduced memory usage of Bayes expiry.
- avoid false positives on Outlook 2003 messages, mails from Mac, Palm, and
localized versions of Eudora, several AOL MUAs, and newer versions of The
Bat!
- new set of French translations from Michel Bouissou
- updated to reflect new Dynablock DNSBL location
- avoids a possible hole that was giving AWL bonuses to
spammer forgeries on some networks
- miscellaneous bug fixes
print correct path to config files in spamd usage message.
Remove DNSBL rules using *.easynet.nl (shut down today, see http://abuse.easynet.nl/dynablocker.html
Update to version 2.60 (fixes PR pkg/23318): Summary of changes since 2.5x ----------------------------------- - spamd supports UNIX-domain sockets - SSL support for spamc/spamd now usable - improved Bayes text analysis - improved expiration of Bayes-DB - better detection of 'invisible text' and other obfuscation techniques in HTML - new RBL (eg SORBS, SpamCop, Osirusoft dropped) - better handling of RBL timeouts - support for Razor V1 dropped - more flexible header and report rewriting - Perl taint mode enabled by default - bug fixes - new rules
Since osirusoft is dead now, we should remove all reference to it from spamassassin. These patches remove all references to osirusoft from the rules files (perhaps leaving some of the comments a tad stale), but leaving information about them in the stats files. This bumps us to 2.55nb2.
- include patch from SA CVS repository to fix a bug with 'spamassassin -r' learning a message without Message-Id as ham (see bugzilla #2030) - depend on p5-IO-Socket-SSL>=0.92 because of bugs in earlier versions - bump revision
Update spamassassin to 2.55 Many small changes since 2.53, but difficult to pick out anything significant.
Update to version 2.53.
This also closes PR pkg/21114 (thanks to Todd Vierling for dynamic PLIST)
Most serious bugs since release of SA 2.50 fixed (hence the 'long'
delay for the Pkgsrc package).
Dependence on procmail removed. You still need a mail delivery agent
but procmail is only a recommendation, not a prerequisite.
Runs on Solaris (somewhat tested on Solaris 8, feedback welcome).
Includes some SSL support for spamc/spamd. Not yet recommended due to
lurking bug(s) (SA bugzilla ID 1751).
Uses Perl module DB_File now instead of NDBM_File. This changes the
name and format of the auto-whitelist database ('auto-whitelist'
instead of 'auto-whitelist.db' on NetBSD).
! This release adds/changes/removes configuration options, PLEASE use !
! 'perldoc Mail::SpamAssassin::Conf' and make sure your mail !
! configuration still works as expected. !
==========================================================================
Changes since 2.52:
- corruption of Bayes db where nspam/nham was getting zeroed, fixed.
- Bayes now has much lower lock timeouts for opportunistic expiry
and auto-learning, to avoid overloading busy servers with an expiry
run. (This may result in occasional "lock failed" messages in the
syslog while you're doing manual sa-learn ops, but those are
not serious; it just means that an auto-learn could not take place
because the dbs were opened by you in another process.)
- NDBM_File does not provide an EXISTS method, worked around.
- BSMTP support (spamc -B) fixed.
- Bayes allowed the user to 'forget' messages they hadn't learned.
- sa-learn broken when installed in a non-standard location.
- spamc was failing to dump message if out of memory.
- add-all-addrs-to-blacklist was a no-op, fixed.
- syslog-socket support was broken, fixed.
- sslspamc compilation fixed.
- SIGCHLD handling in spamd was causing an ugly warning on Red Hat 8.
- user_prefs were left world-writable after auto-whitelist use.
- Razor was zeroing %ENV; protected against this.
- some test failures on 5.005 and with Razor fixed; some tests were
also still using the user's Bayes dbs.
- Windows portability fix in new Bayes journal code.
- dialup_codes now a privileged setting.
- clean PATH env variable immediately upon spamd start; fixed problem
with taint mode failures when getting hostname in Perl 5.005.
- NetBSD: fixed SSL support, spamd start script.
- single-Received-header mails were not getting DNSBL checks.
- some doco fixes.
Changes since 2.51:
- bug 1664: expiry imposed way too much load when a single
site-wide Bayes db was used, fixed
- bug 1672: a typo in a backported patch for 2.51 caused Bayes to
sometimes not unlock the db, fixed
- INSTALL now strongly recommends using DB_File
- some NetBSD support fixes
- bug 1601: option --syslog-socket wasn't implemented
- bug 1260: corrected description of --nocreate-prefs option
Changes since 2.50:
- Bayes locking and concurrency issues fixed
- Bayes expiration was not working; fixed
- spamd was not enabling Bayes after auto-learning without restart;
fixed
- safer way to attach spams, for broken mail clients, using 'report_safe
2'
- a few doco cleanups
Main changes since 2.4x:
- Bayesian filtering, using a Bayesian-style form of probability-analysis
classification. This uses an algorithm based on the one detailed in
Paul Graham's 'A Plan For Spam' paper, along with aspects taken from
Graham Robinson's work, and the chi-combining technique developed by the
SpamBayes project.
- Auto-learning. This trains the Bayesian filter automatically, based on
the results from traditional SpamAssassin diagnosis. It uses a set of
heuristics and separate thresholds to ensure (as much as is possible)
that it trains on guaranteed non-spam and spam. Old, unused tokens are
automatically expired.
- much-improved rule set. A whole new set of rules based on Message-Id
analysis is now in place, which accurately detects forged headers from
a wide range of spamware. Many inaccurate rules have been dropped.
HTML tests much improved, with a set to detect image-only spam.
- new default format for detected-spam messages; the message is
encapsulated as a MIME part, with a preview and the spam report
in the main part of the message.
- Score sets. Based on whether you are using just SpamAssassin rules,
adding network tests, and using a trained Bayesian database,
SpamAssassin will use a set of scores appropriately to gain the
maximum degree of accuracy.
- Italian, Polish, Spanish, French and German rule sets and translations.
- Much improved reliability with spamd. The problems with signals
have been cleared up thanks to a pipe-based child tracking system,
and all spamd-hanging bugs reported have proved unreproducable.
- Unicode problems with Red Hat 8 and perl 5.8 fixed. Works on Perl
5.005, 5.6.x, and 5.8.x.
- Taint-safe. SpamAssassin runs with perl's taint-checking enabled for
better security.
- Razor 1 support is now officially deprecated.
- "spamc -c" was not working, fixed. This fix required increasing the
revision of the spamd protocol; only difference is that now more than
one protocol header can appear in the reply from spamd.
- all fixes from 2.44 included.
Remove incorrect 'free()' from libspamc.c (used in 'spamc'). Patch copied from stable branch of SA CVS repository. On other operating systems 'spamc' was reported to cause a core dump if 'spamd' was not running. At least NetBSD/i386 1.5.3 seems not to be as severely affected, I only got 'spamc in free(): warning: junk pointer, too high to make sense.'.
Maintenance update to 2.44
Parts of patch-ag and patch-ah as well as complete patch-aa could be
removed again, they are now included in SA 2.44 (see below).
#### official release announcement ###############
This is a bug-fix release, which fixes the following bugs:
- Backport fix for Bug 1306: Possible buffer overflow in libspamc when
running in BSMTP mode (patch 1.15 -> 1.18)
- Backport workaround from Bug 526: Failed sanity check because of
clobbered STDOUT (patch 1.147 -> 1.148)
- Backport fix for Debian Bug 160206: Insufficient buffer in libspamc
(patch 1.8 -> 1.9)
- Backport fix for warnings in sed_path (patch 1.141 -> 1.142)
- Backport fix for Bug 1127: Existing lowercase x-spam-status header
kills SpamAssassin (patch 1.40 -> 1.41)
- localized %ENV to fix problem where Razor2 erases the PATH so DCC
and
pyzor don't work, etc.
Note that this is *not* 2.50, which offers Bayesian filtering etc. These
bugs are already fixed in the 2.50 CVS tree, but that is not yet ready for
release. This is a stable maintainance release only.
Fix buffer overflow in "spamc" program can be remotely exploited. Bump package revision.
Changed the rc.d script to account for different behaviour of load_rc_config in NetBSD 1.6. This resolves PR pkg/18928 by Frank Cusack (fcusack at fcusack com). The rc.d script is now called on 'shutdown'. Included fixes from SA CVS repository (2002-10-21) to minimize impact of Razor2 on the environment vector, especially PATH. Bumped PKGREVISION.
Update to 2.43
Item 1) was already provided by 'inofficial' patch-af for 2.42 (now
removed).
Two new patches (-ag and -ah) from the SpamAssassin-current repository
work around a roblem with razor2 timeouts.
Logo 'ninjabutton.png' is now in the correct html directory.
Official changes:
1) AWL change reverted; instead of decreasing the AWL bias gradually to
allow frequently-seen addresses to get into the "nonspam" area, it now
behaves like 2.31 did, in that the AWL simply represents the
long-term average score from that correspondent.
2) core-dump bug in spamd worked around, _except for the "-m" switch_.
The "-m" switch relies on signal handling in the Perl interpreter,
which seems to have some bugs we cannot work around reliably on some
platforms, so its use is no longer recommended.
3) some portability fixes for SunOS.
- Setting PKG_SYSCONFBASE in /etc/mk.conf works now (Thanks to Urban Boquist). - Included fix for bad AWL behaviour which will also be in 2.50 (maybe 2.43) (ie AWL works the same again as in SA 2.31). This causes revision bump.
Update to 2.42.
Uses buildlink2 and module.mk. Some perl scripts for rule developers
(in PREFIX/share/doc/spamassassin/{masses,tools}/) and a small SpamAssassin
logo (PREFIX/share/doc/spamassassin/html/) are now included.
New netbsd_lists.cf file to reduce false positives on NetBSD lists (so
far, only some rules for netbsd-bugs).
Changes:
- bug fixes
- new, better scores (intensive testing was done to improve on 2.40 and
2.41)
- netbsd rc.d script works now with NetBSD 1.5 and 1.6
- management of addresses in the automatic whitlist now easier with
dedicated options (--add-addr-to-whitelist, --remove-addr-from-whitelist)
Update spamassassin to 2.41. Major changes include: - SpamAssassin now *REQUIRES* procmail for local delivery support; "-P" option is now the default. Unless you use procmail, Mail::Audit, KMail, or an MTA-level integration, do not upgrade blindly, your mail *WILL* spill all over the floor in a big mess. - significant speed increases, mostly from Matt Sergeant and Dan Quinlan - bugs in whitelist_to, all_spam_to and friends fixed - rules which were causing too many false-positives removed or fixed: DOUBLE_CAPSWORD, UPPERCASE_25_50, PARTIAL_RFC_2369, MSGID_CHARS_SPAM, many others - lots of rule fixes, and lots of new rules
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
Rename pkgsrc/mail/p5-Mail-Spamassassin to pkgsrc/mail/spamassassin.
spamassassin is already present as p5-Mail-SpamAssassin (how obvious... NOT!)
Add spamassassin-2.31: Spam identifier and blocker SpamAssassin is a mail filter which attempts to identify spam using text analysis and several internet-based realtime blacklists. Using its rule base, it uses a wide range of heuristic tests on mail headers and body text to identify "spam", also known as unsolicited commercial email. Once identified, the mail can then be optionally tagged as spam for later filtering using the user's own mail user-agent application. In its most recent test, SpamAssassin differentiated between spam and non-spam mail correctly in 99.94% of cases. Since then, it's just been getting better and better!
