Except for the problem of failed mail in a list expansion -- on which
matter I agree with Rich Wales -- EXPN struck me as a good idea for
handling mail to multiple lists, or to a person and a list.  As is,
Rich is going to receive two copies of this letter -- one direct, and
one via the list expansion.  A sufficiently smart mailer could use
EXPN to discover that Rich is on the list, and not send him a separate
copy.  (We'll ignore the fact that this particular note is going via
uucp to an SMTP host; it wouldn't really change anything if it weren't.)
