When I run qmail-mini using docker on EC2 instance , the mail always in
queue and can't post out , anybody can help ?

There only have a file "run" and a dictionary "supervise" in the
path /service/qmail-send/log/

the log in /var/log/qmail/current is this:

The 25 port is opened ,  the ECS server is a little special , it has two IP
address one is the private address, another is the public IP , when run
command ifconfig , can't see the public IP only can see the private IP .

and can I use docker exec -i run 465:25 that specify port to 465 ?
