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. -- Regards Eustrop
