DKIM fail if WHM adds Message-ID, should be Message-Id
I created a client library to send emails for a webapp.
After connecting to the SMTP server with credential setup in CPANEL, and
then do NOT add Message-Id header, the DKIM signature 'h' record created by
dovecot/WHM is wrong, and a Message-ID (with a capital D) header is added,
invalidating the generated DKIM signature value.
This causes outlook, yahoo, gmail and other email
