It's a dovecot configuration error. The login has clearly worked, so stop fussing with the firewall. You need to look in /etc/dovecot/conf.d/10-mail.conf and set 'mail_location' to where the user's email is stored. If you are using Maildir then it will probably be mail_location = maildir:~/Maildir if mbox, then probably mail_location = mbox:~/mail:INBOX=/var/mail/%u but adjust the paths to where things are actually stored. You will, obviously, have to set your MTA to deliver the mail to the correct location and in the correct format as well. P.
