 Are you using clamav-milter? There are was such trouble with clamav-milter
from clamav-devel before Apr 2004 on FreeBSD 4.9 (sendmail 8.12.9p2)
 I had that problem with 1.5 minutes or more while transferring single
message to sendmail with clamav-milter. Sendmail has no trouble without
clamav-milter or with other one (For example - spamass-milter-0.2.0_1 port)
 Clamav was fixed for that bug, but real problem could be (on not to be)
inside sendmail.

P.S. I am not sure that my message will be posted to freebsd-security@,
     but you can forward it to upcoming discussion if it's interesting.
