Is the network port of IMAP/POP3 service correct in Thunderbird?
Is your IP address blocked in iptables firewall?
Hello!
Thanks for answering my post.
It is correct, I can send / receive messages with thunderbird using a private address. It is very strange when I use the normal configuration, as always with mail.myserver.com, I can not send messages on the local area network with mail.myserver.com, but I can do it from the outside.
It's so strange, there's no ip blocking in the firewall, no additional configurations ...
