Maildir problem

[netnet.hu - HelpDesk]

Hi

My maildir is /mail/netnet.hu/"username"
I was configure dovecot for this using text user database in 
/mail/netnet.hu/user.txt

currently gy...@netnet.hu is an existing adress at /mail/netnet.hu/gyuri. 
Content is:
   cur  dovecot.index  dovecot.index.cache  dovecot.index.log  new  tmp


I can't configure postfix to delivery mail to this folder.

Can see my config at http://www.netnet.hu/main.cf


Thanks for help!
