Hello,
My Proxmox Mailgateway serves 3 email domains, domain1.com, domain2.com, domain3.com. Domain1 and domain2 are in the same subnet as mailgateway and all are working. The 3rd domain3.com is on another location. I am trying to setup domain3 to use PMX Mailgateway on location 1 as smarthost. But having difficulties. It is unable to establish any connection.

I have port for external and 26 for internal. So domain3 is trying to connect on port 26 to send out emails. Relay domain3.com is added and also the subnet is added in the truested network.

Any suggestions?
 
The issue has been solved. It was due to domain3 not being able to connect to the location 1 IP for some reason. It is now working as expected.
