The relevant option dkim_sign_headers is unspecified.
https://www.exim.org/exim-html-current/doc/html/spec_html/ch-support_for_dkim_domainkeys_identified_mail.html
says in that case, "the header names recommended in RFC4871 will be
used"
https://www.ietf.org/rfc/rfc4871.txt:
"header fields SHOULD be included in the signature, if
they are present in the message being signed:"
My signature looks to have all RFC4871 headers, but my message
definitely does not have them:
h=Date:Message-Id:Subject:To:From:Sender:Reply-To:Cc:
MIME-Version:Content-Type:Content-Transfer-Encoding:Content-ID:
Content-Description:Resent-Date:Resent-From:Resent-Sender:Resent-To:Resent-Cc
:Resent-Message-ID:In-Reply-To:References:List-Id:List-Help:List-Unsubscribe:
List-Subscribe:List-Post:List-Owner:List-Archive
I'm testing with exim 4.89-6 from debian.
Should this be happening? How can I make exim only sign headers that are
in the message I send? Thanks in advance.
