Here is the message one of my clients received"

They want us to stop using port 25. Is this complicated? It is small Windows 2000 network, nothing fancy, the good old stuff before active direcrory (which I am sure many of you use and like) We also employ a Sonic Wall, but they have been of no help in this matter.

Turned out there were a few viruses and things that had passed the incoming Norton Corporate, but which showed up on a full scan. Those I used to do randomly when I had an opportunity -- the user would be away. Malware programs turned up more. (What can you do with the kids these days!?)

What should I do to follow the non port 25 protocol in MS product? Or would it be something I change in my webserver? Or Firewall (Sonic Wall)? I know that I have changed the numbers many times for different apps, but this is critical.

It's a 2000 network running about fifteen XP PCs , all running Symantec Corporate AV, frequently washed by Malwarebytes and more.
