And always is defined as share/examples/rc.d
which was the default before.
This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.
This was discussed on tech-pkg in late January and late April.
Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.

amavisd-new-2.2.1 release notes
SECURITY:
- add support for the pax(1) archive decoder, which can handle tar/cpio/pax
archives (including legacy format variants). Due to limitations in cpio
(and in Archive::Tar), for security reasons it is preferred to decode
such archives with pax and no longer with cpio; please add a line:
$pax = 'pax';
to amavisd.conf and verify that the program pax is installed on the system
(and in the jail if running in chroot);
- perform additional tests at startup time on the proper protection
of the configuration file;
- add file name extensions wmf, emf and grp to the example list of
banned extension, according to recent Microsoft security bulletins;
suggested by Stephane Lentz;
- introduces 'clean but inconclusive' av scanner result to avoid a specialized
or quick partial av scanner like jpeg checker to claim mail is clean
when all other general purpose av scanners fail (see below);
INCOMPATIBILITY:
- removed some legacy $*_ldap variables, as they are no longer needed;
These variables were still declared but ignored in 2.2.0 for compatibility
with older amavisd.conf files. Such variables need to be removed from
the amavisd.conf if they are still present there from older versions,
otherwise Perl will complain with 'Global symbol ... requires explicit
package name";
OTHER FIXES:
- files_to_scan and decompose_mail are now able to remove unexpected
directories which may have been left behind by some failed decoding
and were causing temporary failures and mail delivery retries;
error recovery problem after failed unarj reported by Ralf Hildebrandt;
- error recovery code in files_to_scan and rmdir_recursively now tries to
change protection on directories and files, and retry if the first attempt
to access them fails because of denied permission;
- pre-load some additional Perl modules needed by SA when running in chroot;
- add module Net::LDAP::Search to a list of pre-fetched modules;
omission pointed out by Paul Jacobson;
- when quarantining is disabled by keeping $QUARANTINEDIR undefined,
the log entry and administrator notification message inappropriately
suggested that mail was quarantined, which in fact (appropriately)
it was not. Setting $QUARANTINEDIR='' did work as expected.
Reported by Sascha Lucas;
- avoid the use of Encode::is_utf8 due to a Perl bug (still present in 5.8.5)
where Encode::is_utf8 on tainted utf8 character string produces false;
- modify safe_encode() to guarantee the result is a string of octets,
not a string of UTF-8 characters; it saves some unnecessary work in
further processing and keeps MIME::Entity from UTF swamp when running
in chroot; problem pointed out by Branko F. Gracnar;
- avoid braindead Perl default where an empty regexp implies the last
successfully matched regexp, which (if not being very careful) brings in
some completely unrelated last-executed regular expression;
- change kill 'TERM' into kill 'KILL' when a forked process within run_command
and run_command_consumer gets into deep trouble, to avoid exit handlers
being invoked in the subprocess (which could lead to two processes trying
to clean the same set of temporary files);
- in an old sendmail setup using the amavis(.c) helper program without
LDA arguments, avoid inappropriate warning:
"WARN: no recips left (forgot to set $forward_method=undef using milter?)
and return status 0 instead of 99 when message is to be blocked, as the
helper program amavis(.c) does not recognize status 99 in this situation
and inappropriately passed it on to sendmail; reported by The Mindflayer;
- the @bypass_header_checks_maps is now able to also bypass the bad header
checks as provided by MIME::Parser; inconsitency reported by CRivera;
- avoid some Perl warning messages; thanks to Bill Landry;
CHANGES AND MINOR NEW FEATURES:
- add configuration variable @newvirus_admin_maps (and $newvirus_admin,
along with corresponding SQL field 'newvirus_admin') which works like
the existing @virus_admin_maps (and $virus_admin), except that it sends
virus administrator notification to specified e-mail address only for newly
encountered viruses which have not yet been encountered since the amavisd
startup. It makes use of by-virusname counters in the SNMP counters
database. If more than one child process starts working on infected
message containing a not-yet-accounted-for virus, there might be more
than one 'first time' notification, this is not a malfunction. Both
the @newvirus_admin_maps and the @virus_admin_maps may be enabled,
each (possibly both) would receive their notifications as appropriate.
A useful setting is to globally enable only the new virus notifications,
and additionally enable _all_ administrator notifications for internally
originating mail only (by the use of policy banks);
- provide separate configuration variables @banned_admin_maps and
@bad_header_admin_maps, along with corresponding SQL fields
'banned_admin' and 'bad_header_admin'; their function was previously
covered by @virus_admin_maps, which now only still controls administrator
notifications in case of viruses;
- introduces 'clean but inconclusive' av scanner result to avoid a specialized
or quick partial av scanner like jpeg checker to claim mail is clean
when all other general purpose av scanners fail:
in av scanner entries (lists @av_scanners and @av_scanners_backup) give
an extended meaning to undefined fourth argument (the 'match for clean'
list or regexp). The interpretation of the fourth argument is now:
4. an array ref of av scanner exit status values, or a regexp (to be
matched against scanner output), indicating NO VIRUSES found;
a special case is a value undef, which does not claim file to be clean
(i.e. it never matches, similar to []), but suppresses a failure warning;
to be used when the result is inconclusive (useful for specialized and
quick partial scanners such as jpeg checker);
Also modified example jpeg checker entry in amavisd.conf accordingly.
- NOD32 av scanner: changed @av_scanners entry to match the new version
of the scanner; thanks to Nejc Skoberne;
- added @av_scanners entry for File::Scan;
- when preparing a SQL SELECT clause for white/blacklisting lookup,
take into account a relative position of ? and %k in the
$sql_select_white_black_list template to improve flexibility
of specifying the clause; suggested by Matt Petteys;
- reduce the log level of some more common and harmless log messages;
- macro %p and the log entry now reports full policy bank path,
not just the last loaded policy bank name;
- added LDAP attributes amavisWarnVirusRecip, amavisWarnBannedRecip,
and amavisWarnBadHeaderRecip; by Joel Nimety and Michael Hall;
- renamed LDAP attribute name amavisSpamModifiesSubject to
amavisSpamModifiesSubj in order to match the documented LDAP schema;
noticed by Kees Bos, patch by Michael Hall;
- add support for ripOLE decoder, which attempt to extract embedded documents
from MS OLE documents (MS Office) (http://www.pldaniels.com/ripole/,
by Paul L Daniels)); ripOLE is still experimental/alpha code;
To be make amavisd-new find the installed program 'ripole', add the:
$ripole = 'ripole';
to the amavisd.conf; suggested by David Wilson and Noel Jones;
- allow multiple occurrences of command line option: -c config_file
and execute the provided configuration files one after the other;
based on a subset of functionality provided as a patch by Davor Ocelic;
- a slight improvement (in default $map_full_type_to_short_type_re)
in classifying mpeg and some other multimedia files;
- several minor code cleanups;
- add a recommendation by Daniel J McDonald to a documentation file INSTALL:
If different UID is preferred for an AV scanner, a solution for
ClamAV is to add user clamav to the amavis group, and then add
AllowSupplementaryGroups to clamd.conf;
- enclosed a simple demonstrational Perl program amavis.pl, which is
functionally much like the amavis.c helper program, but talks the new
AM.PDP protocol with the amavisd daemon. See README.protocol for the
description of AM.PDP protocol. To be placed in amavisd.conf:
$protocol='AM.PDP'; $unix_socketname='/var/amavis/amavisd.sock';
Usage: amavis.pl sender recip1 recip2 ... < message.txt
- documentation updates;
under share/examples/rc.d. The variable name already was named
RCD_SCRIPTS_EXAMPLEDIR.
This is from ideas from Greg Woods and others.
Also bumped PKGREVISION for all packages using RCD_SCRIPTS mechanism
(as requested by wiz).
New in 2.2.0:
MIME traversal now includes MIME container parts (e.g. multipart/*,
message/*), making them visible to banned rules. This version
preserves original zip archives for virus scanners if the archive
contains any zero-length members. New short types 'dll' and 'empty'
makes blocking recent viruses more flexible, including their
unsuccessful propagation attempts. It recognizes standard Unix
archives and unpacks Debian binary packages. The LDAP modules were
rewritten. The handling of double errors was improved. This version
supports mail size limits and Mail::ClamAV 0.12. A new AV entry
'check-jpeg' can test JPEG images for validity.
New in 2.1.2:
This release fixes (hard) blacklisting and whitelisting on static
lookup tables, which was failing to match any sender. The 'neutral'
sender notification, which was joining the Subject and the Message-ID
header fields in some situations, has been fixed. The signal and
error handling in code sections holding BDB locks is now more
thorough. A new %e macro is provided that evaluates to a best guess
of the originator IP address collected from the Received trace.
New in 2.1.1:
The default use of $banned_filename_re, which was lost in 2.1.0,
was added back. A fix was made for inappropriate log entry in SQL
whitelisting, complaining about unexpected wb field value. Missing
import of &ca was added to the amavisd-new-courier.patch. A default
directory is now provided with delivery method "bsmtp", if not
specified. The Mail::SpamAssassin::Plugin::Hashcash module is
pre-loaded with SA 3.0.0, and Mail::SpamAssassin::SpamCopURI with
URI::* is loaded for older SA versions. Small enhancements were
made to amavisd-nanny.
New in 2.1.0:
The use of BerkeleyDB is now optional. The configuration files were
cleaned up, and a small new amavisd-nanny utility that shows the
status of all child processes and checks for vanished or stale
processes was included. Two important bugfixes were made in the
ACL and SQL lookup code along with numerous other fixes and small
improvements. Users of 2.0 should upgrade to this release.
into the bsd.options.mk framework. Instead of appending to
${PKG_OPTIONS_VAR}, it appends to PKG_DEFAULT_OPTIONS. This causes
the default options to be the union of PKG_DEFAULT_OPTIONS and any
old USE_* and FOO_USE_* settings.
This fixes PR pkg/26590.
amavisd-new is an interface between message transfer agent (MTA) and
one or more content checkers, e.g. virus scanners, SpamAssassin, etc.
It is a performance-enhanced and feature-enriched version of amavisd
(which in turn is a daemonized version of AMaViS or amavis-perl).
amavisd-new is normally positioned at or near a central mailer, not
necessarily where user's mailboxes and final delivery takes place. If
you are looking for fully per-user configurable and/or low-message-rate
solution to be placed at the final stage of mail delivery (e.g. called
from procmail), there may be other solutions more appropriate for your
needs.
