Hey at all,
i want to use the PMG for my relay-servers. So in my case the current mail relay servers are sending via port 25. Are any solutions on PMG site to send mails via port 25 for relaying?

Best

For outgoing mails you have to use the internal port, which is 26 by default.
And your sending mail server has to be added to the trusted networks.

Port 25 (external port) is used for external mail, which PMG then relays to your internal mail servers.
