[Dovecot] newbie question

Hello all,

just managed to install dovecot as imap server on a Suse Linux box. Now running fine with mbox format. A question regarding maildir or mbox. The MDA (in my case sendmail, Mlocal = procmail) stores mbox format. Do have to modify the local mailer to store maildir format or does dovecot convert automatically from mbox when I tell dovecot to use maildir format?

Thanks, for any hint.
