Ports 993,995,465, 143,100 (all except 25) not responding
« on: March 09, 2021, 03:41:23 PM »
Hello,

On my server all email ports except 25 reject connections (firewall is open, doesn't even connect from local host).

Postfix is running. What is wrong then?

Thanks.

Depending on your Country and ISP it isn't enough to just open the ports in the CWP Firewall.

If i don't do a PortForwarding on my Router i can allow everything in CWP and it won't work.

Have you done a proper PortForwarding if you need to do?

Here you can check if your desired ports are reachable from outside: https://www.yougetsignal.com/tools/open-ports/
