First off, I didn't install it, nor do I have access to it, so I can't really give more information than what's in this mail unfortunately.

However if the bug hasn't been found and fixed yet, this report should be enough to find it.

I had a user that was sending mail with the following in the "From: " field: Jason T. Collins <jcollins@valinux.com>

Mailman would send mail back to jasont.collins@valinux.com and say the person wasn't subscribed. The problem went away when I had him remove the "." after the T in his name.

My guess is that some regular expression in mailman is being fooled by the "."
