Hi Steffen,

MTA is qmail and doesnt know anything about users. dovecot uses 
usernames for mailboxes. lets say

/var/mail/userA/Maildir
/var/mail/userB/Maildir

both users have mailaddr XY at example.com mapped in Active Directory. Now 
when mails arrive lda is called like

dovecot-lda -d XY at example.com <mailto:dafan.zhai at securepoint.de> -m INBOX

and theres my problem.
