You didn't tell us what method you are using to run qpsmtpd (e.g.

I am using forkserver, the server is not thrashing (it's a 15k scsi box and
has avg TPS of ~250), i'm not using the check_helo or check_earlytalker
either.

I have resolved the issue. The issue was with a BIG-IP that is in the
picture. I thought i could have dismissed it because it was not reaching any
connection limits. The problem was with timeouts. The BIG-IP tested the
connection every 5 seconds and had a timeout of 16 seconds. This caused the
server to be removed if it took longer than ~16 seconds to respond dropping
those active connections mid stream.

I do have another question regarding timeouts. I'm seeing a ~5 second delay
to get the 220 response. Where is this defined? Is it customizable?

Thanks again.
