How to set up iptables for Thunderbird?

Question

linux

The problem is this. There is a dedik on Centos. Inside, everything is controlled by cPanel. I'm trying to set up Thunderbird to receive mail from this server. Ports 143 and 25 are open in iptables but Thunderbird can't get the settings. If you stop iptables, then everything works.
What should be iptables for Thunderbird to work?

Answer 1
