Unable to create account self-hosted?

Thanks for sharing all details !

I’ve pinged the domains mail and welcome and they resolve to my public IP address. The root pings to my private IP. Could this be the problem? I can change the hosts file, if so.

Yes, I think that your problem could be related to this.
But hosts file may not be the solution, as some scripts/programs may forcibly use DNS requests.

After running step #0, what gives
docker-compose exec mariadb mysql --user=root --password=$MYSQL_ROOT_PASSWORD -e "select * from postfix.domain;"
docker-compose exec mariadb mysql --user=root --password=$MYSQL_ROOT_PASSWORD -e "select * from postfix.admin;"
docker-compose exec mariadb mysql --user=root --password=$MYSQL_ROOT_PASSWORD -e "select * from postfix.domain_admins;"
?

I’m running low on free time right now, I’ll think about your problem and post back later …
