Hi Michael,

i already got it configured to authenticate users against a mysql database. 
It works fine. I have simply no experiences with the virtdomain features. I 
already read all the documentation stuff but to be honest from my point of 
view there are some things which are not covered. As already said currently 
the main problem is that i'm not able to create a mailbox for a user 
user at domain.tld. Don't know why. Anyway i'll have a look at web-cyradm.
