Hi Elise, >> dovecot-2.3.11.3_1 >> Providing the correct email address and password.

With using BSD usermanager, adding a user named > 'i...@mydomain.com' is converted automatically to user 'ilse'. I am not sure I understand your problem. Who exactly is converting the username? Is it Outlook or dovecot or your BSD usermanager? I am aware of a problem where Outlook tries to guess the username from the provided e-mail address and its AS aka artificial stupidity guesses wrong. cheers, Michael
