"Been here once" also doesn't work if mailing lists are used.  For
example, a message sent on MIT-MC.ARPA to UNIX-EMACS@CMU-CS-C.ARPA has
to be able to return to MIT-MC.ARPA for recipients who were specified
in the mailing list on CMU-CS-C.ARPA.  This could happen several times,
if there are nested communities of interest, or local delivery lists.
