Amavisd
From Logicalwebhost-Wiki
Amavisd is the connection point where Postfix or other mail server can call, and Amavisd then will call up a bunch of helper programs, normally various scanners you can specify in a config file which lives here
- /etc/amavisd/amavisd.conf
Amavisd has changed pretty significantly since it was called just Amavisd, the one you want is Amavisd-new, it's better, tastes great, runs better
[edit] stuff it does
- raises or lowers spam scores for specific addresses
- raises or lowers the thresholds for spamassassin
- change where it kills it
- change where it tags it
- change if it bounces, deletes or whatever
- blacklist / whitelist certain senders
- calls up whatever anti-virus scanner you might have running
- can submit anti-virus samples to whatever company's submission system
