However, I do understand you need to support MuA's login with either johndoe or [2]johndoe@domain.name. I have a solution for you, but it's based on MySQL/MariaDB. I use Exim (MTA), Dovecot (2.4.1), and SOGo (Groupware/Webmail).
Perhaps a crude solution might be to use the auth_default_domain setting.
