Hi,

I'm having a few problems with our smtp mail, and I was hoping someone could
pint me in the right direction.

We have site www.ourdomain.com hosted on our ISP, who also provide our pop3
email (mailserver.ourdoamin.com). Internally we have our Win2003 active
directory domain (ourdomain.com), Win2003 smtp server and DNS.

I've set up our DNS so ourdomain.com is a forward lookup zone. Then added
mailserver.ourdomain.com as an mx record in our DNS. IIS has an smtp virtual
server setup for server1.ourdomain.com (default), GUID._msdcs.ourdomain.com
(normal) & ourdomain.com (custom).

Now, I can send and receive email externally, I've tested this with my home
account, and hotmail account, and it pretty quick. However I can't seem to
send email internally. I've emailed other people, and got them to email
me/other people and messages aren't getting through.

What could be the matter?

Cheers

Ben

Why are you using an internal SMTP server?  Is it set to use your ISP
as a smart host?  You don't appear to have an internal POP server, are
you using the ISP for POP?  Have you looked at your SMTP server logs
to see what's happening?  Have you tested your internal SMTP?  See:
