Yes, I know. I am the author of listhandler.module. :o)

Listhandler sends the mail, IIRC.

There shouldn't be a problem at the sending end. I was rather thinking
that the retrieving end could get clogged up if there are a lot of mails
sitting in the inbox. The worst thing that could probably happen is that
threading gets mixed up, but one never knows.
IOW, there should be a mechanism to check threading once in a while and
fix it if for example parent mails were received after their children.

Matt and I once tried to write a module that allows subscribing etc to
mailman lists through Drupal. It didn't get further than a proof of
concept, but you might want to revive it. Beware: It relies on
Snoopy.inc to do some screenscraping. You can find it in the attic of
the contrib/nodules cvs (mailhandler_api).
