vqadmin messes up

Hi,

I use qmail for a couple of years now, but after a reinstall on my 
server, vqadmin does weird.
Everything on the mailserver works (it delivers the mail, so that aint a 
problem) except for vqadmin.

i deleted everything which was vqadmin (updatedb; locate vqadmin) and 
installed it clean.

Only it doesn't make a difference, it gives me "Domain has no 
postmaster!!" error when looking at my made domain.

Qmailadmin works great, so i dont see what i am doing wrong.

Who can help me?

thanks!
