Email address 'user at' not in local domain

I have a single-domain setup with alias names and configured my 
kolab.conf so that every user gets specific mail aliases within every 
alias domain.

I can only change a users data via kolab-webadmin, when logged in as 
directory manager, since the webadmin otherwise complains:

"Email address 'user at' not in local domain"

Only Directory Manager somehow bypasses that restriction.

Same Problem here:

Best regards
