I'm running Bind for my domain. I do not have a zone for 192.168.0. setup in

server for the machines on my private network. Will turning off DNS lookups for
ESMTP in the webadmin interface be a way to check if this is the problem? Do I
need to hack in a 192.168.0. zone? I assumed that the DNS lookup was on the
domain in the TO and FROM addresses not the connecting machine... am I wrong
here?

I don't know if that's really your problem. The description just sounded like something I ran into recently: I started seeing 60-second ESMTP delays waiting on reverse-lookups for machines on the local network.

If you telnet to port 25, do you get the ESMTP greeting immediately, or does it hang for a fixed time? If you see it immediately, then you have some other problem.
