Public bug reported:

We're running Mailman 2.1.14 and have recently begun using mm- handler-2.1.10 from the contrib directory as MTA for sendmail. Everything appeared to work fine, but after a few months we were alerted by one of our users that no mail was delivered anymore to one of his lists. The list's name is mathematica-admin. It turns out that mm- handler strips the -admin part and tries to deliver the mail to a list named mathematica, which does not exist. We had a small number of other lists with the same problem. I've created a patch that fixes it and another small issue (a variable is passed to a subroutine, but a global variable is actually used there).
