I used proxmox as the mail gateway and associated with my exchange. But now when I set up the pop client, pop can only receive mail but can't send mail. How do I configure it
I have the same problem as you now, from the Internet to the firewall to proxmox to exchange2016. The problem is now that my exchange2016 is deployed in an external computer room. All clients use POP3 mode to receive and send emails. You said to use port 30. Map to port 25 of the gateway. I don’t quite understand this. Please give me some advice.The problem has been solved!
To sum up: my environment is from Internet to firewall, then to proxmox, and then to exchange.
The desired effect is that the mobile terminal can use pop protocol. At this time, after normal settings, you need to show a 30 (non conflicting arbitrary port number) - > 25 (standard port) from the external network to the internal network on the firewall, and then set the sending server port of the mobile phone to 30
