I have two branches. In one of the branches in DMZ i have MailRelay(SMTP Server) what manages mail traffic. In anothet branch i have, only Domain Controller, SharePoint Server and SQL Server dedicated for SharePoint. Now i need to set SharePoint Server for
be able to send mail to Internet(Outside the branch). For this purpose i want to configure in Outgoing E-Mail Settings in Central Administration Mail Relay, that is in my other branch. My problem is, that these two branches have not direct Lan connection
and each time i need to open, let's say HTTP or HTTPS between them, i have to open in FireWall port 80 and 443.
So my question now is: what port i need to open in FireWall in first branch for SharePoint be able to Connect to MailRelay(SMTP Server). In another words, by what port SharePoint talks with SMTP Server?
