Topic: iRedMail container won't send after restart

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version 1.5 (MySQL)
- Deployed with iredmail/mariadb:nightly
- Linux/BSD distribution name and version: Ubuntu Server 18.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? no
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.

451 4.3.0 temporary lookup failure
====

If I deploy the container fresh, everything works, and I can send and receive emails

If I restart the container I get the 451 4.3.0 temporary lookup failure message in postfix logs

If I replace the container by running the docker command again then I can send emails again

I'm not sure what to do to enable the iRedMail container to send emails persistently after restarting the container.

Re: iRedMail container won't send after restart

Looks like the container doesn't load config file (the "iredmail.conf" file in tutorial).
