We use mysql auth and support username or usern...@domain.com for logins. Perhaps you just need to edit the auth_username_chars variable in the dovecot config to allow @ symbol in usernames?

I tried dovecot-mysql authentication which works fine but i do not find a way to use 2 different login-formats in my queries. login with abcde and also testn...@example.com should return ok and lead to /var/spool/mail/abcde. Is this possible or i have to make a decision which format to use? Thanks, Andre
