The particular case of the 'message-id' header is generated by the
original sender's mail client.  It is not manipulated by the humbug mail
list software unless it does not exist.

Header fields are case insensitive.  To quote the current standard for the
format of email messages, std11 (rfc822):

        When matching any other syntactic unit, case is to be ignored.
        For  example, the field-names "From", "FROM", "from", and even
        "FroM" are semantically equal and should all be treated ident-

In other words, if you have a mailer that is having issues with
'Message-Id' vs 'Message-ID' vs 'Message-id' (all of which were generated
in the last ~1500 messages), then the configuration of your mailer needs
to be checked.

The copies of all the humbug list messages I receive have the '<' and '>'
brackets around the message-id string.  If they are not there in your
copy, then presumably something in the path is blocking it.
