Just a long shot but check your dovecot settings in the /etc/dovecot/
directory and make sure SSL encryption is optional - not required. Also,
dovecot would be looking for an SSL certificate. We always point that
setting to the SSL certificates at /var/qmail/control/servercert.pem.
And although complicated to setup we get our mailserver certs from Lets
Encrypt.
