[SOLVED] Issue about smtp port cant open public

[anhtung19x9]

Hello, I'm a newbie with Proxmox mail gateway, have read documention but can't find any help. I can see my proxy setting default is

External Port: 25
Internal Port: 26

My PMG have Public IP is A.A.A.A
but I can't connect My zimbra server at AWS to PMG on A.A.A.A port 26. I tried to telnet A.A.A.A on both port 25 and 26, all of its are connection refused. I tried to show all port opening on PMG, below is result:




So, PMG only open port 25 and 26 at Localhost IP. How can I force PMG open port at A.A.A.A ip ?

* make sure you have configured a correct entry in your '/etc/hosts' which makes your hostname point to A.A.A.A
* run `pmgconfig sync`
* restart postfix

I hope this helps!
