[exim] Add DK Results in Header

Greetings,

We have configured Exim 4.71. Incoming mails are being directed (PIPE) to
~/.procmailrc, which is scanned by SpamAssassin. We are trying to add DK and
DKIM results in email header for all *incoming emails*. We are able to add
DKIM result in header successfully. Un-fortunately, we are not able to add
DK result in header. It seems, DK support is dropped in Exim 4.71. We also
could not find any straight forward instruction for verifying DK for *incoming
emails* alone and adding its result to header. DomainKeys signature are
available on incoming mails header.

It will be a great help if any one help on adding both DK and DKIM results
on header such as
