Probably a namespace issue.  The imap daemon is telling you there's not
new mail.  So wherever it's looking it sees no mail.  So either it's
looking in the wrong place, and the configuration isn't correct.  Error
logs will inform you about the latter, 'dovecot -n' about the former.
Show dovecot client connection and error logging, and dovecot -n.
