Prior to performing this fix, I can receive ALL emails fine, I just can’t send via port 25 (since my ISP blocks it!)

Post performing this fix: I can send ALL emails just fine, but I can no longer receive emails from outside my domain.

Any suggestions or tips on why after doing this I can’t receive emails from outside my domain?

Eric, you must have it listen on BOTH 25 AND the new port. Read the instructions a little closer.

Simply copy/paste the existing smtp line and change the name and port (we’ll use port 26 in this example).

Copy, then change

Thanks for the tip. Did everything, netstat reports listening not problem. QMail however is not responding on this port. Should something also be changed in the QMail config. I am using Plesk 8

Thanks.

I’m running Red Hat Linux, and I can’t figure out where to change my SMTP Port as my ISP Blocks 25?
