LISTSERV 1.8d can do equivalent hostname aliasing.  The best example is:

 [log in to unmask] = [log in to unmask] = [log in to unmask]

However this only works for the hostname side of the address.  If want
paul@... = paul.franco@... you need a master lookup transposition table and
probably a machine dedicated to running this.  (Actually LSMTP 1.1b can do
address re-writing between real names and "appearance" names and might be
applied to handle this).
