Incoming mail and other statics.

Tom, the port configuration are changed the external port is 26 and the internal port is 25. But if I look for mails send or recive in the tracking center, they appear. the problmem is only with the statics.

changing the ports on the GUI is not enough. you also need to make sure that your firewall/router and your internal email server sends the emails to the configured smtp port (25 / 26) to our Proxmox Mail Gateway.
