After a bit more investigation at the MTA side, I managed to find out that Mailman processes the subscribe requests alone twice. Subscribing through the web interface makes Mailman process the request once. However, sending a mail without proper commands to mailinglist-request@domain throws ONE error e-mail back, as it should be. So there's this situation:
- Subscription through web interface: OK
- Subscription through e-mail: 2 subscriptions processed
- Other mail to mailinglist-request@domain: OK
Where do you suggest I start looking now?
Look at the actual subscription request e-mail (Bcc: yourself to get a copy). Look for anything strange like two From: headers or e-mail address appearing twice in From: header.
I've done some more checking, it seems that there wasn't a problem
at all (or at least, Mailman is not processing requests twice). Your suggestion made sense... Said e-mails had "subscribe" both in the subject line and in the body, causing two subscription requests to be processed :(((( Despite this being much of a case "all this trouble for nothing", having Mailman process the same request twice for the same e-mail doesn't make much sense (I'd count it as a bug, really). Thanks to everyone for their input on the "problem" :)
