Problem

A Forum reader recently asked:

“I have a server beween my GWIA (7.0.2) and the Internet that does anti-virus/anti-spam. How do I restrict GWIA so that it only accepts SMTP from this server instead of from wide-open sources?”

And here is the response from Bob Mahar …

Solution

- On NetWare: Enable IP filter support in INETCFG and filter SMTP access except for the allowed address.

- On Windows: Enable the firewall and allow SMTP from the allowed address.

- On Linux: Use IPchains or whatever from the allowed address.

You get the idea. Or, you could use a real firewall upstream as well.
