[Dovecot] [Fwd: Bounce action notification]
Anyone have ideas why this happened? Nothing special in logs, all tss@iki.fi deliveries went OK. Mailman's bounce log is unhelpful. Why does it say it tried to deliver to dovecot@dovecot.org and when it failed it disabled my account? Why doesn't it even bother saying which remote host gave an error? Grepping mail.log for 'This user' shows nothing.

That isn't a terribly helpful error message, since it doesn't include the original e-mail message, with headers, so that you could see what Mailman thought the original Mail-From: address was (which is what is failing here)...

Actually, it does include the bounce with headers. The bounce seems to have originated from 81.3.115.182, which reverse-resolves to canville-182.adsl.newnet.co.uk.
First guess is, something is seriously broken in that host. Another guess is that Mailman just scanned the bounce for subscriber addresses and found tss@iki.fi, given that the bounce wasn't formatted in any standard way.

Duh, of course you are right! I glanced at that block and thought that was the dovecot.org server itself generating the bounce. I concur that the above listed server is the cause of the bounce message; I've seen this before with badly written homemade spam filters...

Right, thanks. I didn't notice that. Banned the IP, hopefully it's not dynamic. :)

I wish Mailman supported some kind of hashes in bounce addresses.

It supports VERP, which should handle this issues nicely. Though it'll require some work on your mta config, it's worth the trouble.

Oh, I hadn't heard of that before. It's pretty much what I want,
although having it unforgeable would be even better. Now lets see if
this message uses VERP or if I broke the list entirely. :)

Success! You've broken my procmail rule for the list. ;)
