UDP port used by Smarter Mail
Problem reported by M G - January 24, 2015 at 8:38 AM
Not A Problem
Hi Guys,

I'm having an hard time find the UDP port/ports that Smarter Email is using on the server. I have enabled the ranges 1024-65535 for the moment and I have no idea how to get exactly what ports its using.
 
Any idea will be much appreciated!

Mike

If I block the ports then then emails are just stuck in the spool so it must use them.

Hi there!
 
I'm not terribly technically inclined so forgive me if I'm wrong with this, but these are the Commonly Used Ports for SmarterMail. I'm not sure if there's a difference between what's listed here and a UDP port, but I imagine if it's not listed in this article then SmarterMail does not utilize them.
 
I'll see if I can get someone a bit more technical to take a look at this for you and correct me if I'm wrong.

SmarterMail uses UDP on port 53 for DNS resolution.

It should be said that port 53 UDP is for DNS only. If you do not run DNS on your smartermail server then you do not need to open this port.
 
I am uncertain about that port being added to the KB since it is not need directly by Smartermail.
