For several years I’ve been running a postfix/amavis filter in front of
our faculty Exchange server. We are an on a University so we do have
contact all over the world involved in discussions about all parts of
the human body - dealing with financial research, and so on. This means
we reluctant to tigthen our level.
$sa_tag_level_deflt = 1.5;
$sa_tag2_level_deflt = 3.0
$sa_kill_level_deflt = 6.31;
Our setup is pretty much a default setup based on packages as delivered
by OpenSUSE with a few handmade supplementary rules added when some junk got
past the filters. On top we have a bl subscription at spamhouse and
running sa-update once every night.
The solution have worked pretty well for the last couple of years - or
at least nobody have complained about the amounts of spam slipping trough.
But lately one of my users have been hit by huge amount of Chinese spam (I
guess), I have adjusted my filters and included Chinese_rules.cf. Futher I
have feed her letters to baisian and that helped somewhat for a couple of
months, but now things is slipping in to this user again. The Chinese
rules seems quite old and might be outdated at this time.
I have temporary placed a sample selection at http://mirror.sc.ku.dk/ahroo1it/
I would be gratefull if anybody would take a look on these and see if I by
accident have disabled some of my filters. Suggestions for improved filtering
would be fantastic to.
Our servers is currently running:
