Hello simos, I have learned most of the LXC from your articles found here and on different forums. I believe your answer is nearest to solution. However, I tried one of your article and caught in this issue which was also a topic on this forum. Link is here .
Exactly what I am trying and failing in?
I have aapanel installed on ubuntu 18.04 (container). I used IP tables to listen default port of aapanel 8888 on Public IP: port. Everything is going good except mail. I can send mail to other domains but can’t get mail from them. My domain to my domain emails are working fine .
