I have just setup up a MikroTik router (RouterOS 2.9), and everything works fine (everyone in the subnet can get to Internet and so on).. But I cannot get the e-mail server working.
I tried to open ports in Firewall - NAT (ports 25 and 100), but I still cannot get througt it. I suppose, I have done the port openning wrong.
So, how should I open those ports, that e-mai could be sent and received? I can ping the mail server. It has static IP address (for example 192.168.0.13).
Please, help, I am new to this OS and tomorrow everything should work (after 8 hours ).
