UUCP mail is specifically handled semantically in the relay syntax for
the embedded responder address.  THis has to be handled anyway, or you
would not be able to send mail from a "normal" host to a UUCP host and
then on to a bang path.

For example, in the address "gang!foobar@fee.com", the address of the
relay host "fee.com" must be accessible.  In other words, only the RHS
is examined, and the bangs are all left-associative.

Heh.  The address rewriting rules for outbound mail will, by default,
replace the 'localhost' before invoking the check_relay ruleset following
rule 98.  If it doesn't, your config file is broken (or, re: our LUSER_RELAY
discussion, perhaps the sendmail configuration macros are flawed).
