Guys,

How are you handling all of the spam that is being sent to postmaster@
addresses. In order to be RFC compliant, you are supposed to have postmaster
active, but since the spammers have now made this a favorite address, how do
you handle it? I'm considering blocking it temporarily to generate rejects
to see if that helps. Any other thoughts?

Stopping Spam for valid and needed accounts is one of the more difficult challenges of spam fighting.

First you have to analyse what kind of Spam you are inflicted with.

Is is spam from Zombies with dynamic addresses?
-> Use according blacklists and greylisting
Is it Spam send from free accounts on Webmailers yahoo, msn etc.?
much more difficult, that would have to be handled with care.
Is it spam send in great numbers from a few clients?
-> Use Anvil, policy-restrictions on mail flow.

Sandy
