[Solved] What ports to open?

[ergocho]

Hi, i recently installed ispCP with (at least like a see) all working, but i have a problem with the mail.

If i send from my webmail to any account, it arrives. But if y send from the cloud to my server, never arrives. I think that maybe can be a closed port in my router, what ports i need to open?
