This part means that Sendmail, for some reason, failed to resolve one
of the addresses involved. Are you using DNS to resolve `localhost'?
Maybe that's why it times out, and it queues the message until the next
time the queue runner wakes up...
Two other interesting bits of information that ay help us find out
what's going on are:
(1) Your sendmail_xxx options in /etc/rc.conf:
# fgrep sendmail_ /etc/rc.conf
(2) The value of `DirectSubmissionModifiers' in sendmail.cf and
submit.cf:
# fgrep DirectSubmissionModifiers /etc/mail/sendmail.cf \
/etc/mail/submit.cf

A minute later, the queue runner wakes up...
