True. I didn't want to suggest that, though, because we weren't told what
mailer he was using: many MUAs fill in a domain-part for you, and that may
not be the same as the hostname. (Pine, for example, will never pass an
unqualified address to the MTA; it guesses the domain-part from a number
of places, such as the "user-domain" field in the setup, which is often
set to a plausible value because it's often used to change the domain-part
of the From address on outgoing mail. That value isn't necessarily the
name of the local host, or indeed of any host.)
