This I s not a dovecot issue I don't think, this is a configuration issue with
your MTA (exit, postfix, sendmail, et al).

This seems very very wrong as the headers in mail messages are not case

Also, I do not think dovecot adds message-id headers at all, and dovecot would
not be involved in sending mail.
