[Dovecot] Disallow creation of (sub) folders

Hi.

Is there a way to prevent users from creating new mailboxes?

In our setup, we've several standard mailboxes (maildir format). Users should use these and only these.

I allready tried to chown the base directory, e.g. /var/mailstore/r/remy/, to root, and delivery still works then, but procmail chown's this back to the users' name. I have a workaround by using symlinks, but I think this is a lame solution.

Another question: when is Dovecot 1.0 supposed to be released for production purposes?

Regards,
