  • 1.  Blocking Outgoing SMTP Port 25 on SEP

    Posted Mar 05, 2011 02:43 AM

    Is the blocking of  outgoing smtp port 25 on SEP possible?

     

    I created a blank rule in my SEPM as my top rule. It blocks remote port 25. When my policies are updated on my SEP clients, I can still telnet to remote port 25.

    Using the same rule (with different port numbers) i am able to block port 80, 21... but i cant do the same thing for port 25.

    Anyone any idea how I can do this??

    Solved. Quite silly though. I have been trying to figure this out for days, and never realised that there is an Email Auto-Protect feature for the AV.

    The way to solve this is, to go to Email Auto-Protect, disable it, or change the outgoing port to something else other than 25.

    It allowed port 25 despite my rule... is because SEP is configured with Email Auto-Protect, with Port 25 as outgoing port. Change/Disable it...will give me the option to disable the outgoing smtp port.
