Much of the spam I used to receive came from forged hotmail.com accounts. Very little spam actually comes from hotmail, so I don't want to just block them since there are some legitimate correspondents of mine that use their mail (heck, I use a hotmail address sometimes when I'm on the road..)Ron Guilmette has patches that do this for Postfix at <http://www.monkeys.com/anti-spam/filtering/additions.html>. I tried them but had too many false positives, even for the commonly forged domains like hotmail. They did catch some spam though it never more than 2 or 3% of the daily filtered total.
SpamAssassin (which is usually called from your delivery agent, not your MTA) does catch these forgeries with very good accuracy. You might want to give it a try. -- Brian Hatch If you think there Systems and there is good in Security Engineer everyone, you www.hackinglinuxexposed.com haven't met everyone.
