(expanding scope due to non-response)

We're working with an ISP that has port 25 blocked. Currently we are using
No-IP's mail relay service. Having recently moved towards a dedicated
service for some of our applications we now have the ability to put an IIS
SMTP service up and want to use it to do the alternative port relaying.

I've gone through the IIS SMTP configuration for relaying as outlined in the
various Microsoft KB articles. At this point I've configured the
appropriate domains, specified our internal server to forward to and set the
outbound connection port to 26. When I send a message to the SMTP server it
basically sits in the queue with no information provided in the event logs.
Does anyone have some pointers on troubleshooting the routing and relaying
components of the IIS SMTP service on Windows Server 2003?

Thanks!
Colin
