SpamAssassin 3.2.5 used in Kerio MailServer's Spam Filter contains a bug causing that all emails sent in year 2010 may get additional 3.188 spam score points. This could lead to marking regular messages as a spam (or blocking the message by the server).
More details can be found at https://issues.apache.org/SpamAssassin/show_bug.cgi?id=6269
Update: The issue is fixed in Kerio MailServer 6.7.3 patch 1. Upgrade to this version to resolve the problem.
1. Edit the plugins/spamassassin/rules/72_active.cf file in KMS installation and change the following line:
original line: header FH_DATE_PAST_20XX Date =~ /20[1-9][0-9]/ [if-unset: 2006]
modified line: header FH_DATE_PAST_20XX Date =~ /20[2-9][0-9]/ [if-unset: 2006]
2. Restart the Kerio MailServer.
- Linux: /opt/kerio/mailserver/plugins/spamassassin/rules/72_active.c f
- Mac OS X: /usr/local/kerio/mailserver/plugins/spamassassin/rules/72_ac tive.cf
- Windows: c:\Program Files\Kerio\MailServer\plugins/spamassassin/rules/72_active. cf
The configuration file can be edited by any text editor. On Linux and Mac OS X running the editor with 'root' privileges is required.
As an immediate workaround please create a new custom spam rule which will decrease the spam score by -3.2 points for every message containing Received header with substring "2010". See the screenshot:
Please note, the workaround has to be removed once the issue is fixed (either by modifying the configuration file or Kerio MailServer upgrade)!
Kerio Connect 7.0 beta, Kerio MailServer 6.7.3 and older
The fix is highly recommended to all KerioMailServer customers running any KerioMailServer version and using Spam Filter for spam classification !
