Maildir with Postfix/Dovecot/procmail/mutt

[bsdperson]

Ok, I have probably screwed up with the mail on my 7.2-stable.

In main.cf:
home_mailbox = Maildir/

dovecot.conf:
mail_location = maildir:/var/mail/%u/Maildir/

muttrc:
set mbox_type=Maildir
set folder = /var/mail/person/Maildir
set mbox = /var/mail/person/Maildir
set spoolfile = /var/mail/person/Maildir

The problem is that as soon as I send a mail to "person" the /var/mail/person file is created where I suppose it should be a folder containing a Maildir/{cur, new, tmp} structure?

To eliminate one problem I renamed .procmailrc but that might have made it worse?

As you see I'm not really sure of what I'm doing.
