A message-id is not an email address.

remote_header_rewrite_domain (default: empty)
Don't rewrite message headers from remote clients at all when this
parameter is empty; otherwise, rewrite message headers and append the
specified domain name to incomplete addresses. The local_header_re-
write_clients parameter controls what clients Postfix considers local.
Examples:
The safe setting: append "domain.invalid" to incomplete header
addresses from remote SMTP clients, so that those addresses cannot be
confused with local addresses.
remote_header_rewrite_domain = domain.invalid
The default, purist, setting: don't rewrite headers from remote clients
at all.
