What ports to forward to server for mail to function correctly?
I recently upgraded to Mountain Lion form lion and am experiencing a MAIL issue (FAILURE)
I beleive I need to restablish or open ports on my router but the common ones don't seem to be doing the trick for users using Outlook. I have the Apple document that talks about the most common used ports but my Netgear router limits me to 20 so I need to narrow down the selction a bit.
Any assistance would be appreciated.
Right now, these are the ports being forwarded: (and yes, many can be eliminated)
