Hi, I've been testing the program on Windows Server 2012 R2 for a few days and I can't get any user to connect to the server on IMAP or POP. I've tried setting a new password for the users, changing the protocol, using SSL, etc. but none of the authentication methods work. On the logs it simply says "S <-- 3 BAD LOGIN failed" for IMAP and "S <-- -ERR Invalid user id/password specified" for POP.

I recreated the setup on Linux without a problem though.
