RE: [Declude.Virus] blocking auto reply messages
Help me out please. Why are we looking for the beginning of an IP address? Also my understanding of these filters is to eliminate sending emails to users that were not the original senders because of a forged virus. Is that correct??? If so wouldn't adding the Virus name to the declude forged tag solve that??

RE: [Declude.Virus] blocking auto reply messages
Here's what works for me: Matt's (Mailpure) ANTI-AV filter works pretty well for me. Then this was discussed last weekend on the list. It involved punishing those that fail the anti-av filter and have a null mail. I have a postmaster-mail filter: MAILFROM0 IS <> MAILFROM0 CONTAINSadministrator@ MAILFROM0 CONTAINSAntigen@ MAILFROM0 CONTAINSAntigen_ MAILFROM0 CONTAINSDLWC-virus-scanner@ MAILFROM0 CONTAINSe500admin@ MAILFROM0 STARTSWITH NAV@ MAILFROM0 CONTAINSNAVMSE- MAILFROM0 CONTAINSNAVMSE_ MAILFROM0 CONTAINSNAVMSE@ MAILFROM0 CONTAINSPOSTMASTER@ MAILFROM0 STARTSWITH root@ MAILFROM0 CONTAINSSymantec_AntiVirus_for_SMTP_Gateways@ MAILFROM0 CONTAINSVirus_Alert@ MAILFROM0 CONTAINSVirus-Alert@ MAILFROM0 CONTAINSVirus-Alert. MAILFROM0 CONTAINSviruschecker@ MAILFROM0 CONTAINSvirus-scanner@ MAILFROM0 CONTAINSvirusmanager@ MAILFROM0 CONTAINSVirus-Monitor@ MAILFROM0 CONTAINSvirusscan@ Then I have a combo filter for the anti-av (called MP-ANTI-AV) and the Postmaster-mail, giving 10 more points. TESTSFAILED 10 CONTAINSMP-ANTI-AV POSTMASTER-MAIL Note, I'm lazy and have the postmaster-mail filter immediately after the mp-anti-av filter in my cfg file. This way I can avoid a couple of other Testfailed filter. If you move the postmaster-mail filter to a different location, you'll need to add testfailed to look for each individual filters and then combo testfailed on those.

Re: [Declude.Virus] blocking auto reply messages
Greg, I like your thinking very much here. Unfortunately this requires knowing all the possible outgoing servers for all of your clients, and because I'm gatewaying a bunch of E-mail, that is near impossible to keep up with. I'm not about to give up on the idea though. My BOUNCER filter that I described is very effective at handling NDR's when they contain original content, even if it is just the headers often times, but yesterday some child porn spammer used a real E-mail address of a customer and generated about 500 bounces, and I estimate that about 50 got through because they contained no content in the bounce such as NDR's sent by AOL. Your filter might be a good way to manage the situation for individual domains that are having problems with real addresses being used, and implemented per-domain when a problem arises. I'm wondering if you are aware of any NDR's that are getting through your setup, i.e. ones that don't contain the headers.
