I've recently set up a mailserver on my PC using VisNetic Mailserver.
Everything works, except for one thing; the users on my mailserver cannot receive mails from other domains like email@example.com
they only can receive mails from other people/accounts on my mailsever
Sending mails to anybody isn't a problem.
Maybe there is something with my ports? I had to setup different ports because my ISP is blocking port 25 and 110.
Maybe other mailservers (like hotmail) cannot communicate through my ports?
Does somebody know how I can solve this?
