Listproc, the clone-implementation of Listserv, also has the NOMAIL flag.
Listar has this functionality as well, as does Mailman (and I think
Sympa and Lyris do as well).
In fact, Majordomo is - as far as I know - the only package that does NOT
provide for this functionality in some way, though I know a few people who
have patched their own copies to give it this functionality. (Usually
requiring admin intervention, unfortunately.)
