Help to configure Mail Gateway (incoming and outgoing)

[phoenix1977]

Hello,

hope you can help me.

I have Proxmox Mail Gateway installed on Vultr but my mail server is external (on A2Hosting), so i have insert the records in the DNS of mydomain.org to point to Proxmox Mail Gateway on Vultr like:

mailgateway 3600 A IP.of.Proxmox.Gateway.on.Vultr
@ 3600 MX mailgateway.mydomain.org

In the Relay Domains tab on Proxmox Mail Gateway configuration section, i insert the domain of the account email info @ mydomain.org
mydomain.org

External SMTP Port is 465
Internal SMTP Port is: 26

This two ports are open.

But doesn't work, i can't receive email.

What missing?

Thank you in advanced.

The Traffic Mailserver to Mailserver is running over Port 25. If you would receive Mails from the Internet your external SMTP Port must be 25.

Internet --> Port 25 (PMG) --> Mail Server
Mail Server --> Port 26(PMG) -->Internet
