Exim will use its own internal message-id (prepended to the hostname) if
you use 'control=submission'. See the 'control' modifier
http://www.exim.org/exim-html-4.50/doc/html/spec_39.html#IX2464
and also the 'message_id_header_text' and 'message_id_header_domain'
options.
My config predates that option so still does it the old way:
warn hosts = +relay_hosts
condition = ${if !def:h_Message-ID: {1}}
message = Message-ID: <E$message_id@$primary_hostname>
warn hosts = +relay_hosts
condition = ${if !def:h_Date: {1}}
message = Date: $tod_full
