Just a quick question,
One of our colleagues has brought up an interesting question regarding
Exim's implementation of DKIM signing.
I've looked at the docs
(
http://www.exim.org/exim-html-current/doc/html/spec_html/ch54.html)
and before I spend hours on this, is there any way to control which
headers are actually signed?
We are seeing an issue with GMAIL where our own generated message ID is
getting signed, but GMAIL are stripping this off, replacing it with
their own and breaking validation, even with 'relaxed' set on.
I seem to recall in OpenDKIM you could specify the headers to sign, but
I can't see an obvious config option for it in Exim?
