Hello gang,
Running Mainman 2.01 with Postfix, with many different domains. Occasionally when looking at the mail logs, I see a "Mail forwarding Loop" messsage for <listname>@machine.hostname. Nothing seems to be out of the ordinary otherwise... I can go thousands of messages without seeing this, and other times I see quite a few.
Could this be related to messages bouncing? It's right in the log during a mass send, and almost looks like Mailman is sending itself the message.
Ideas?

I don't run Postfix on my mail server (though I do run it on my workstation as a null client), but I had a similar problem with sendmail.
The messages for which I got those errors, however, were not delivering at all. You should doublecheck that.
The problem comes when your mail server goes to lookup the mail exchanger for the domain the message is addressed to and finds itself, but the server is not configured to accept mail for that domain...
Let's say your mail server is supposed to recognize crazyperson.net as a local domain... but you don't have that configured properly. A message is then handed by a local client (mailman) to the server destined for the (local, but unrecognized) domain crazyperson.net.
So it says "Hmm... where does crazyperson.net mail go? I don't recognize it. Lemme check the domain record. Hmm... MX is poopyshoes.crazyperson.net... and a quick nslookup says that's 172.16.44.9... wait, I just sent that message and it came back to me... but it said I just sent it and now I want to send it again... oh dear, I hate being a dumb machine and unable to prevent this silly recursion! I should make a note in my log so the adminstrator can help me!"
Anyway, that's the best I can describe what was going on with me. And yes, I always give my daemons personalities. You should hear my curmudgeony NFS daemons. lockd is particularly amusing. And httpd thinks he's pretty cool stuff, the little twerp.
I don't know what else might be causing your problem, but that's why I got a similar message from sendmail.
Thank you very much for indulging an old woman in her failing years. J.
