For the most part, UUCP machines that do routing run the smail
program and handle the domain!user convention (all the official
UUCP-Internet gateways do).  So yes, you can mail to an ARPA site
using all-bang paths.  Mail to me using ...!uunet!epimass.epi.com!jbuck,
for example.  This type of address is completely unambiguous (unless
it goes through a rerouting mailer but that's another war); the details
are discussed in the RFC by Mark Horton (forget the number).

See above.  If c is your gateway machine and runs smail or other
software that supports host.domain!user, you can just mail to
a!b!c!host.domain!user.
