Odds are you have your MTA configured to do DNS lookup verifications
of message envelopes.  This can and will chew significant time.  It
will chew even more time if you don't have a local cacheing name
server.

Note: There are second order problems with turning off DNS checks
under Sendmail (see prior messages from Chuq).  Recommend: Lose
sendmail and get a decent MTA.
