Re: Port 25 blocked?

Good morning.

I have taken the following lines from "Using McAfee VirusScan"

VSE 8.0i has new intrusion protection features such as port blocking used in
firewalls and protection for files, shares and folders. Open VirusScan
Console. Right click on Access Protection and click Properties
Under Port Blocking, you can specify rules to block a port or group of ports
separately for inbound and outbound network traffic. Check the rule to enable
it. By default, outbound SMTP e-mail traffic on port 25 is blocked

I hope it's usefull for you
