[Dovecot] virtual users with mysql

[Andre Hübner]

Hello List,

we use in our system cryptical Usernames for dovecot etc. and authenticate users against shadow/passwd

User abcde is loging in and gets data from /var/spool/mail/abcde  and /home/popuser/abcde

Now we want to make it possible that users can log in also with emailadresses.
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 testname at 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
