Asunto: [Exim] [PATCH] Make domain-part of Message-ID configurable.
Hello,
the attached patch adds a new global option message_id_header_domain,
which is used as domain-part in generated messages-ids and defaults to
primary_hostname. (inn uses domain in readers.conf for this purpose).
It accepts a string (not expanded) containing [A-Za-z0-9.]*. The patch
is against exim 3.22.

Feel free to criticize, and/or tell me how to make it better. If
this is sorted out I'll provide an update for spec.txt, too.

Please Cc me on follow-ups because I am not subscribed to the list
(Mail-Followup-To is set).
             TIA, cu andreas
