But the username in the authentication db is completely independent of any localpart that might be used to deliver to a mailbox - access to which is authenticated by providing creds for that username. I don't see how the fact that MTAs may or may not consider localparts to be case-sensitive has any bearing on the case-sensitivity of usernames stored in the authentication database.
