modoboa VS docker-mailserver

modoboa: http://modoboa.org good choice for samll company and teams (support limite Nd quote)

I've had good success with Modoboa. It's the only one I've found that has both a GUI and decent LDAP integration. There are a few containerized versions out there, though you should definitely be sure to update modoboa after deployment if you use them: https://github.com/modoboa/modoboa

https://github.com/modoboa/modoboa - Not dockerised last I checked and a little more in-depth

I have used Roundcube docker-compose-fpm.yaml, which looks like it can be easily extended with docker-mailserver

However... For a live fire, in production setup I would push people to use a meta package like docker-mailserver, mailcow, mail-in-a-box or modoboa as it's better to have someone else set the sane defaults to prevent you from missing that one line in you config.

docker-mailserver

Privately I use https://github.com/tomav/docker-mailserver and an external Roundcube instance, which is ideal if you have only a few mailboxes. For updating, a docker-compose pull and a docker-compose up -d are all you need. They also offer a script that makes administration much easier. It can be used to manage mailboxes and aliases as well as things like DKIM. If you have a larger number of users, Mailcow is also a good option, but it is also much more complex and resource hungry.
