Dear all
Where should I put the Authentication-Results header? Exim here is a
"border" SMTP MTA for an internal mailbox store and MUAs
I am evaluating DMARC and making use of the handy (scraped from https:/
/github.com/Exim/exim/blob/master/doc/doc-txt/experimental-spec.txt):
add_header = $dmarc_ar_header
However, according to https://tools.ietf.org/html/rfc7001 the header is
a "trace header" which leads to:
https://tools.ietf.org/html/rfc5322#section-3.6.7
I have now gone RFC blind and would be gratefull for some direction on
where the Authentication-Results header should be placed. We have
several modifiers at our command for placing headers:
http://www.exim.org/exim-html-current/doc/html/spec_html/ch
-access_control_lists.html
"This is done by specifying “:at_start:”, “:after_received:”, or
“:at_start_rfc:” (or, for completeness, “:at_end:”)"
For example, at the moment I see something like the dump below. Should
the A-R header be where is is at the moment or just above the
"Received: from hummus.csx.cam.ac.uk" line as my reading of the RFCs
implies?
If it should be elsewhere then the experimental-spec example could be
usefully updated accordingly.
Cheers
Jon
