Maildir in Dovecot

Hi,
How do I create maildir format in dovecot-IMAP.
Shall the steps down will help me out.
#rpm -ivh dovecot*
#makdir /home/alice/Maildir
#cd /home/alice/Maildir/
#makdir new
#mkdir cur
#mkdir tmp
To automate this I can put them in /etc/skell.
But My question is will not this create a permission issue?
Any other configuration needs to be done beside /etc/postfix/main.cf
Regards,
Subho
