Just a wild ass guess, but does your password backend expect "me", or "me@mydomain.com" (which is what it was given).
It was expecting me@mydomain.com, but that wasn't the problem. Turns out PostfixAdmin was hashing the passwords with MD5 and Dovecot was looking with ARGON. No wonder I was getting password mismatches!
