Difference in Return-Path (envelope) and From: (header) - spam messages, how to react?

2012-03-28 Thread Rafał Radecki
Hi all. Currently we have some amount of spam with different Return-Path and From fields. What to do to filter it? Should it be done in postfix (at mta level) or maybe in spamassassin? I think that SPF could be used but what about domains which do not have proper spf records? Best regards, Rafal.
