           Summary: Mark DKIM signed messages
           Product: kmail
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde at tilman-klaeger.de


Version:            (using KDE 4.3.0)
OS:                Linux
Installed from:    Unlisted Binary Package

With DKIM the sending mailserver adds a signature to the email headers,
similiar to a GPG signature. The receiving mailserver then validates the
signature with a public key published in the DNS record of the sending domain,
on success, a header is added to the email.

It would be cool, if KMail could mark messages, that passed DKIM similiar to
the way GPG-Messages are marked!


dkim-milter produces following header:
Authentication-Results: mx.rcpt.domain; dkim=pass (1024-bit key)
    header.i=@sender.domain; dkim-asp=none


Google uses the following header (first SPF, then DKIM):
Authentication-Results: mx.google.com; spf=pass (google.com: domain of
sender at sending.domain designates xxx.xxx.xxx.xxx as permitted sender)
smtp.mail=sender at sending.domain; dkim=pass header.i=@sending.domain


KMail could also do the signing and verification on its own, but imho this is
the job of the mta, not the mua.
