     I'm sure they're using something like address plussing, though
the examples I've seen to date are simply username+ at blah.edu.  I don't
want mailman to strip the + out, but I would like it to not freak out
and hold such messages for approval (list set up with posting by list
members only).

     Is there any way to set up an email alias for a given user in
mailman?  That would be relatively simple, just tweak the subscribe
CGI form to automagically subscribe both variations.
