You need manually configure you MTA for store email's in this path in maildir format, for example changes for Exim MTA http://forum.ispsystem.com/ru/showthread.php?t=4200

Ok, that worked once I removed a user and re-added them. Where does Dovecot find this configuration? My /etc/dovecot/dovecot.conf had mail_location = maildir:~/Maildir added to it, but was not working.
