[Dovecot] deliver to root account

Hi list.,

With dovecot-rc7 I am getting the following error when delivering to root while queue gets bigger with failed attempts:

deliver(nobody): stat(/root/Maildir) failed: Permission denied deliver(nobody): stat(/root/.dovecot.sieve) failed: Permission denied deliver(nobody): lstat(/root/Maildir/cur) failed: Permission denied

What am I missing?

In postfix/main.cf home_mailbox = Maildir/ mailbox_command = /usr/local/libexec/dovecot/deliver

Thanks !
