Hi all !

Portforward port 25 to 587

Plesk for Windows 11.5.30

We are have setup smtp like this

If i telnet 587 from outside and on the server no problem all is working great !
If i try telenet 25 from outside i can not connect ! But if och do it from the server i can connect !!
It is probably something i missed, but i can not find the correct settings !
Firewall is open for 25 and 587 !

Please help me out !

Best regards jonas
 
it is depended on firewall only. Are you able to telnet port25 on same server. If yes then check the same with other machine which is in different network. ISP do block port 25 in their firewall to stop spamming.
