Some ideas...

by AruJammer In reply to Microsoft exchange server ...

-See if you have port 25 open in the firewall (if using SMTP).

-Look in you NAT configuration if they are setuped right.

-Check if you have Mail Relay rights from your ISP and that this is setup in your Exchange.

-Do some test with MS lookup.

Google for MS lookup..and see if you can get any records of your site...try a test.


Next use telnet to check your mail server

Router

by AruJammer In reply to TELNET

I'm not familiarized with this model of router,

Standard in routers there some option to open ports in firewall settings, go in your router firewall settings and open port 25 for all incoming traffic.

Check your NAT configuration, here's the logic;
You have to give access to all WAN traffic, with service SMTP (port 25),to you Exchange server ip-adres (same SMTP service on port 25).

Have you enter "Fully-qualified domain name" and "Smart Host" in Exchange?
