Original GitHub issue: https://github.com/modoboa/modoboa/issues/3514

I tried to setup the project locally for development, but there is a problem with the Dovecot Docker integration.

There is an error during docker compose up:

2025-03-30T16:03:37.004784257Z doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/auth-custom.conf line 10: disable_plaintext_auth: Unknown setting: disable_plaintext_auth

I commented out the line, then got another error:

2025-03-30T15:52:43.543494260Z doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/auth-custom.conf line 12: passdb { } is missing section name

It's probably an issue with Dovecot 2.4.
The docker compose file is using the latest tag but we should restrict to version 2.3 until we upgrade the configuration.
Try with dovecot 2.3, it should work.
