Okay I usually do not have a problem with SMTP but I cannot get this server
to send mail. Here is the setup:

Small home network
1 Domain Server running Windows 2000 Server and Active Directory, No DNS
1 Windows 2000 Server (web server)
1 2Wire DSL/Wireless Network Modem/Firewall
1 Dynamic IP (using No-Ip to mimic Static IP) points to 2Wire Modem
Firewall routes all SMTP and web requests to Web Server.

I have several small gaming websites going to this server with No-IP urls
(that look somethig like this name.servebeer.com) which need to be able to
just simple emails.

Okay I have setup my Firewall to allow SMTP both ways. I have my Default
SMTP setup as follows:

General:IP Address is setup to Server Port 25
Access: Anonymous Access,Basic Authentication,Windows Security Package
Connection Control: All except list below
Relay: All except list below ** will adjust these to to just this computer
once it is working.
Delivery Advanced: Masquerade Domain - None
Fully-Qualified domain Name - not sure what to put on this one?
Security: Administrators only operators.

I do not get any errors when using simple CDONTS test page but it just sits
in the Queue and thats it. The log does not seem to give me any helpful
information either the event log has the following error:

"Message delivery to the remote domain 'gmail.com' failed for the following
reason: An internal DNS error caused a failure to find the remote server."

Any help with this would be greatly appreciated (I am a programmer and
Server setup is something I am not very knowledgable about).

Thanks

1) Use CDO, CDONTS is deprecated.

2) Make sure your ISP allows traffic on port 25.

3) Make sure your DNS can properly resolve the detination domain's MX
record.

4) HOW TO: Test Windows 2000 IIS SMTP Services Manually
