Just wanted to note that the expn.c program I posted to this list a while back
does use the fully qualified address first, and then tries the local name only
in the event of a mailer which can't deal with requests to EXPN or VRFY
addresses with @ in them. It also tries both EXPN and VRFY, so except for
mailers which don't support either, it gets a response.
