Version 2.5.2 of amavisd-new is available at:
http://www.ijs.si/software/amavisd/amavisd-new-2.5.2.tar.gz
The 2.5.2 is primarily a maintenance release over 2.5.1.
amavisd-new-2.5.2 release notes
BUG FIXES
- in a milter setup log_id was left undefined, which resulted in log lines
without id, and a SQL constraint violation "Column 'am_id' cannot be null"
when logging to SQL was enabled. The bug was introduced in 2.5.1;
problem reported by Martin Svensson;
- suppress a quarantining attempt if the message also needs to be archived
to the same location (same sql key or same local filename);
reported by Wazir Shpoon;
- adjust $socketname in amavisd-release to match its default counterpart
in amavisd (i.e. /var/amavis/amavisd.sock); reported by Stanley Appel;
NEW FEATURES
- add snmp-like counters for PenPalsSavedFromKill, PenPalsSavedFromTag3
and PenPalsSavedFromTag2, which correspond to the number of messages
where spam level would have exceeded a corresponding level had there
not been for (negative) score points contributed by pen pals lookups.
Note that for any message only one of the three counters could
increment, the one corresponding to the highest level crossed.
To find more information about rescued mail messages, search the log
for a string 'PenPalsSavedFrom' (available at log level 2 or higher).
Practical value: mail saved by pen pals from being blocked usually
indicate false positives by SpamAssassin; examining rules which
contributed most to the score may indicate these rules need adjustment;
- when preparing a SQL SELECT clause in lookup_sql, provide an additional
placeholder %a in a clause template, which is much like the existing %k,
but evaluates to an exact mail address (i.e. the same as the first entry
in the %k list), which makes it suitable for SQL pattern matching;
suggested by Daniel Duerr;
- macro supplementary_info can supply information on two additional
SpamAssassin tags: AUTOLEARNSCORE and LANGUAGES if corresponding plugins
are enabled in SpamAssassin; see README.customize for the complete list;
- provide two new subroutines available for calling from config files:
include_config_files() and include_optional_config_files(), each take
a list of filenames as arguments, and reads & evaluates them just like
normal configuration files specified on a command line (option -c
or a default amavisd.conf). This provides a simplified and uniform
mechanism for 'including' additional configuration files, which formerly
could be invoked through a perl do() function. The only difference
between include_config_files and include_optional_config_files is that
the former aborts if some specified file does not exist, while the later
silently ignores specified but missing files. Both/each subroutine
may be called multiple times, recursion is allowed (but some sanity
limit to recursion is provided); based on a suggestion by Gary V.
Example line in amavisd.conf:
include_config_files('/etc/amavisd-custom.conf');
OTHER
- provide a workaround for a crashing altermime by removing its leftover
temporary file which would otherwise cause a temporary failure:
TempDir::check: Unexpected file
problem reported by Dennis A. Kanevsky;
- add a mapping to 'doc' for a result 'Microsoft Installer' from a file(1)
utility; it seems like versions 4.20 and 4.21 of file(1) (possibly earlier
versions too) misclassify all MS Word, Excel, and PowerPoint documents
as 'Microsoft Installer'; problem investigated and a workaround
suggested by Noel Jones, Mike Cappella and Michael Scheidell;
- add a mapping to 'asc' for a result 'COM executable for DOS' from a file(1)
utility; it seems like later versions of file(1) can misclassify a text
in a GB2312 character set as a COM file; reported by Daniel J McDonald;
- updated AV entry for ESET NOD32 Linux Mail Server again - command line
interface (nod32cli): added a status 3 (e.g. corrupted archive) back to
the list of clean statuses; the 3 was removed in 2.5.1 as the entry
was substituted with the one from a NOD32 documentation; reported by
Tamás Gregorics;
- updated AV entry for 'F-Secure Antivirus for Linux servers' to cope
with version 5.5 and later; a new entry provided by Peter Bieringer;
- when a command line option -g requests changing of group ID, do so
by calling POSIX::setgid, after also attempting to assign to perl
variables $( and $), which may not work correctly on systems where
group ID can be negative (like group 'nobody' being -2 on Mac OS X);
follows a SpamAssassin problem report 3994, investigated
by Sidney Markowitz;
- when an AUTH command parameter (RFC 2554) is supplied on a MAIL FROM
SMTP command but AUTH support has not been previously offered
(like when authentication is disabled by an empty @auth_mech_avail),
no longer treat the situation as a fatal error:
503 5.7.4 Error: authentication disabled
but mercifully ignore the parameter and just log an informational
message. This is a deviation from RFC 2554, but makes it friendlier
for those insisting on running amavisd as a Postfix pre-queue smtp
proxy; suggested by Alexander 'Leo' Bergolth;
- adjust the list of pre-loaded perl modules required by SpamAssassin;
- internal: pass a mail message to SpamAssassin as a GLOB instead of an
array reference, saving one in-memory copy of a message during a SA call;
- internal: make it slightly easier to switch message digest from MD5 to
a Digest::SHA family by turning a hard-wired key length into a parameter
(admittedly it is still ugly, requiring a change in three places for
switching); also pave a transition from Digest::SHA1 to Digest::SHA;
- documentation: updated files README.postfix and README.postfix.html
now include a section 'Advanced Postfix and amavisd-new configuration'
explaining a multiple cleanup service architecture; thanks to
Patrick Ben Koetter; retired file: README.postfix.old
- documentation: updated README.sql-pg to include a faster alternative to
purging a SQL logging database: the alternative 'DELETE FROM maddr' on
PostgreSQL runs faster by a factor of 1.5 to 2 from the one previously
suggested;
- suggestion: when using SpamAssassin plugin Rule2XSBody
(available in more recent versions of SA), adding an entry like:
Mail::SpamAssassin::CompiledRegexps::body_0
to the @additional_perl_modules list allows preloading of compiled rules.
Adding the following two lines to amavisd.conf adds the directory name
containing modules with compiled rules to Perl modules search path and
allows Perl to find the listed module(s):
my($sa_instdir) = '/var/db/spamassassin/compiled/3.002001';
unshift(@INC, $sa_instdir, $sa_instdir.'/auto');
