Forgive me, you misunderstand. The original post is posted with a legitimate from: address, so I send from legitimate, but it gets sent to a bogus address. So the original post gets posted and because the from address is legitimate from the mail goes through. However, because a reply gets sent from a bogus address and sent to a bogus address then regular expression filter that I've set up discards that mail. Let me define what I mean by bogus. I set up in a slightly complex filter in milter-regex to only accept mail that comes either from or to accounts that actually exist from the mail server's perspective The filter something like this. I am by no stretch of the imagination a regular expression expert, so it took me a long time to figure out how to build this. This filter has the effect of blocking out the ping pong of bounced messages stating that a server doesn't exist. Which allow my server to work with legitimate mail. IllegitimateTo = header /^TO$/i /(\.email at ddress.1\>|\.email at address.2\>)/e LegitimateTo = header /^TO$/i /(\<email at ddress.1\>|\<email at ddress.2\>)/e LegitimateFrom = header /^FROM$/i /(email at ddress.1|email at ddress.2\>)/e LegitimateMail = $LegitimateTo or $LegitimateFrom discard not $LegitimateMail discard $IllegitimateTo Then there is of course the junk that comes in to legitimate addresses which is blocked out with simple filters. So milter-greylist blocks out around 80% of the garbage that comes into my server. milter-regex blocks out, oh, I would venture to guess about 99% of the rest of it. Mailscanner / Spamassassin, takes care of viruses and marks everything else that it thinks is spam or phishihng attacks as such and it provides baysian filter learning which is cron jobed on a per user basis through fetchmail. Legitmate mail gets through most reliably. The junk gets discarded. Oh.. one more note. If you notice the "IllegitimateTo" a lotta mail will try to sneak under the wire of filters by adding a dot infront of a legitimate email address. And that line takes care of it And we should really stop discussing this here. If you post a reply of course I will read it. But, I think this isn't a MailScanner mailling list. :) Eli -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
