Thanks! I do indeed get a hang for a fixed period of time when connecting to the ESMTP port. Thanks for pointing me in the proper direction... now it's just a DNS issue. Thanks again!

I'm running Bind for my domain. I do not have a zone for 192.168.0. setup in bind. However, I do have some entries in the /etc/hosts file on the email 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.
