Group, Below I have pasted log entries demonstrating some unexplainable tempfails I've been seeing in the last couple days.
I've tallied about a dozen different senders to whom this has happened, but there seems to be one sending domain in particular, that is getting hit by this when they try to send to us. The messages ultimately do come through, but only after dozens of attempts, and up to a day's delay. My server's sendmail load varies throughout the day, but averages 20-40. Sendmail's confQUEUE_LA is 48, confREFUSE_LA is 60. Sar shows the machine is typically busy throughout the day (averaging 5-20% CPU idle. Disk activity is usually around 8-18% (I use a RAM disk for /var/spool/MIMEDefang), and disk freespace is never a problem. The log entries show that the milter is tempfailing the message, but I cant find a cause. Sendmail's confLOG_LEVEL is 14, and confMILTER_LOG_LEVEL is 9. Anyone have any suggestions?
