Hi There

Having an external SMTP issue with 2003 SBS.

The server is not accepting connections on Port 25 from external only!. Telnet to Port 25 on the internal network is 100%.
The DNS, F/Wall, Port Forwarding is all 100% corrrect - all other port forwards for RDP, SSL etc are working fine.

The Server just won't allow me to connect from external to Port 25.

To date I have:
Re-Run the Internet/E-mail connection Wizard
Re-installed Exchange from master SBS disks
Re-applied all Service Packs/Updates
There is no malware of any kind on the machine
All external DNS for mail forwarding is 100%

I am truly stuck - any help is gretly appreciated.
