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_domainsetting.https://doc.dovecot.org/2.3/settings/core/#core_setting-auth_default_realm
Default realm/domain to use if none was specified. This is used for both
SASL realms and appending @domain to username in plaintext logins.
If you only have a single domain name, this should work. The method I am using allows a larger scope. You can loging as user1 or user1@domain1, etc If a user provides just "username" I run a query that tries to match it against domain1, domain, 2, domainM. Whichever matches first is used.
