AMS (Andrew Mail System, from Carnegie Mellon University ) used to do
this, and Cyrus might as well.  I don't know if anyone is still using
AMS though.  cmu.edu and pitt.edu are two common domains that used it
(I went to CMU and AMS was still in heavy use at the time, but I think
that they have switched over to Cyrus now).

Your users can always subscribe twice, once with the + and once
without, and set one to nomail.  You could fairly easily write a
script to do this if you like.  It also wouldn't be hard to write a
filter that got invoked before mailman and converted From
"foo+ at bar.edu" to "foo at bar.edu", but that is kind of ugly.
