Hi Folks.

I'm running Sendmail 8.9.1 and it is REALLY slow opening SMTP sessions from
machines that are behind a NAT. (The NAT's WAN interface has a real IP
address, but the machines on the LAN side are using the 192.168.0.x
addresses).

Thinking it may be a DNS lookup issue with the 192.168 addresses, I put in
an in-addr.arpa table so that 192.168.0.2 resolves to 192.168.0.2. That
doesn't help.

Any other ideas? Anyone else run into this?

Here is an email header for a message that I sent myself, if that will help:
Received: from [192.168.0.2] (PPP-01.connecticom.com [209.3.110.190])

	for <kitt@connecticom.com>; Fri, 27 Nov 1998 09:42:37 -0500 (EST)

This is an entry from the sendmail maillog:
