Yes it is.... The problem wasn't coming from Mailscanner, but from milter-regex. I've got regular expressions blocking bogus email addresses. Unfortuneately, I've had to include the mailing list domain to the acceptable to: addresses because fedora's mailing lists seem to send to the list rather than to individual users. OK.... I'm getting fedora-kde posts now.

If others have some similar set up, where bogus email addresses are discarded, they might not even be aware that they aren't getting any email from an active mailing list. As such they wouldn't be getting anything and not be looking into it. And they, consequently not participate. Especially since they might try to post and not get any reply. Just a thought.

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$/i /(\.email@ddress.1\>|\.email(a)address.2\>)/e LegitimateTo = header /^TO$/i /(\<email@ddress.1\>|\<email(a)ddress.2\>)/e LegitimateFrom = header /^FROM$/i /(email@ddress.1|email(a)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.

Anyway... it's not a dot or space but, the period infront of the email addresses in front of the line: IllegitimateTo = header /^TO$/i /(\.email@ddress.1\>|\.email(a)address.2\>)/e means a string including what follows after the dot. There seems to be a lot of "malmail" that is designed not to get to any recipient, but only to clog up mail servers with no such address ping pong repsonses. False recipients and mail with recipient strings that include legit email address but also have infront of the string garbage characters. That line takes care of those.
