This is an IMAP username that seems to be formatted similar to an e-mail
address because your setup is built like that.
Usernames (IMAP or otherwise) and passwords are not part of any email
spec, but checking them case-sensitive sounds like a good idea in general.
You should make sure that the username string used by dovecot-auth is
formatted according to what your setup dictates (i.e. probably all
lowercase). Probably you need something along the lines of:
userdb {
driver = passwd-file
args = username_format=%Lu /path/to/file
}
