Max,
It would be awesome if you could post a summary of what your setup is,
what you were trying to accomplish, and the configuration you came up
with after all this work with Aki and the rest of the team.

Digging through the entire chain would be a chore and while I've
enjoyed reading it all, I've already forgotten what the original setup
was you're were working on!

As a bonus, this writeup will help you in the future if you run into
problems again.  :-)

Aki> Ah. This is because you have a mistake in your userdb query:
Aki>    SHA2(CONCAT(username, random_key), 256) AS
Aki> userdb_mail_crypt_private_password \

Aki> should be
Aki>    SHA2(CONCAT(username, random_key), 256) AS
Aki>    mail_crypt_private_password \

Aki> userdb_ prefix should only be used in passdb **or** passwd-file.
