Please describe the scenario.
Do you want to send or receive email?
In UCS, when the mail server app is installed, port 587 is open by default.

I guess that the question is related to the relayhost setting.
Postfix Small/Home Office Hints and Tips says:

I havent verified it, but it looks like adjusting UCRV “mail/relayhost” is the way to go.

cheers,
