    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" :)
