I'm pretty sure you're mistaken. It's handled by an automatically
created entry in /var/lib/mailman/data/aliases , a file that Mailman
manages for you.

I _think_ you should let Mailman do it as per above.
Here's a post by Mailman chief coder Mark Sapiro re: mailman-loop address:

It's for _bounces_ of password reminder mailings. The special sending
address is used just in case those messages also bounce, to prevent
formation of a bounce loop. You really shouldn't fool with it.

VERP to the rescue. Enable it, at least long enough to identify the
problem child. (Long term, might leave it off, as there are
disadvantages. See first link about that.)
