[fetchmail] fetchmail to Maildir

FF,

    How is fetchmail configured to deliver mail to Maildir?  It is functioning 
correctly sending to /var/mail/username

On FreeBSD 4.7
cvsup of the ports then installed these from /usr/ports/ with make install

Fetchmail > Postfix > Maildrop > Maildir

Will I need to write /maildroprc file for Maildrop and have it filter the mail 
to Maildir?

Thank you for your guidance
Jason
