I use postfix with mysql which forwards mail to a content filter (
amavisd-new ) which does the virus scanning and Spam detection. Using Spam
assassin I have DCC, Razor, and Bayesian Learning. All mail is forwarded
through unless its a virus --> onto Cyrus, then I have Sieve read the mail
headers to filter all Spam into a junk folder. If Spam still comes through
I just have all my customers forward the mail to
[email protected]
<mailto:
[email protected]> . A cron job runs at 6am every morning to
learn from these Spam emails and put them into the Bayesian database. I
only use one RBL which is relays.ordb.org, I don't like RBL's really because
they have some pretty idiotic polices not to mention they're so secretive.
Spam really isn't a threat - its more annoying then anything else - some
customers like to read through it sometimes - I cant stop them if they want
to. Yet every two days, all mail that's in the junk folder is automatically
purged.
Regards,
Patrick
