That would be right.  But Michael indicated that he was pulling
his mail with Pop3.  If he's on a serial line or behind a
firewall, his machine might not find the real host either
... over to you, Michael?

Also, do a tail -f /var/log/maillog and tail -f /var/log/messages
when you try to pull, and see what sort of messages issue from
sendmail.  That would give you a bit more info on what's going on
before (as I imprudently suggested in my last note) you start
hacking on the sendmail configuration file.

Cheers,
