Zimbra Random Port Connection

Post by csniper »

Hello,

Last week I set up a zimbra server for testing purposes.
When I look at the firewall logs, I see that the server wants to connect to random ports from port 25.

I saw this from the server as well. You can see from the file I attached.

I'm wondering why, shouldn't e-mail servers normally connect to port 25 other than port 25?

Server: Ubuntu 20.04.5 LTS

Thank you.
