I've set up a small closed network. I'm using this little network for a demo. I'm observing 15 second delays in sending -- can't seem to see why there would be any appreciable delay.

The config is:

The network IP addresses are 192.168.50.*

All systems are running Windows XP Pro SP 2.

A DNS server (SANS -- a scaled-down version of Posadis -- http://www.posadis.com/news/050108-sans?DokuWiki=a77bd42d2aea0d787b15fbd85e76fdc4) runs on 192.168.50.10.

Other machines have IPs 192.168.50.20, .30, .40. Each has a name.

The names are:

.10 sysa.com
.20 sysb.com
.30 sysc.com
.40 sysd.com

Each runs James.

The James config.xml on each is the one shipped with James (with host names set appropriately -- I am using SMTP AUTH).

The good news: Mail moves between systems.

The bad news: There is a sending delay. The delay is very similar for e-mail sent between all systems.

Here's an example header of a mail send to [EMAIL PROTECTED] from [EMAIL PROTECTED]:

Return-Path: <[EMAIL PROTECTED]>

          for <[EMAIL PROTECTED]>;

I'm stumped. Also not 100% sure of what log should show me what the problem is -- I don't see any obvious "hang" in any of the logs.
