I'm not sure if Message is ignoring the value of
`message-required-mail-headers'.

My guess is that your message-id like this:

  Message-ID: <8b21e2aa979f8c1944fc0b5ca4be1e5c@posteo.net>

is generated by your sendmail program.  I use msmtp which has an option:

‘set_msgid_header [(auto|off)]’
  When to set a Message-ID header: ‘auto’ adds a Message-ID header if
  the mail does not have one (this is the default), and ‘off’ never sets
  a Message-ID header.  Message-IDs have the form ‘hash@domain’, where
  ‘hash’ is a hash over some values that uniquely identify the mail, and
  ‘domain’ is either the value of the domain command (unless that is the
  default value ‘localhost’), or the domain part of the envelope-from
  address (if available), or the host name of the SMTP server.

Maybe you want to check your sendmail program.
