--- Comment #3 from Wolfgang Breyha <wbreyha@???> ---
IMO fix for 1721 does not fix this issue.

I testet with a message signed and reverified by the tools provided with
perl-Mail-DKIM-0.40-7.fc23.noarch

I attached my testmessage.

The message verfies with
$ perl /usr/share/doc/perl-Mail-DKIM/dkimverify.pl <dkimtest_signed.eml
originator address: postmaster@???
signature identity: @sproing.at
verify result: pass
sender policy result: accept
author policy result: accept
ADSP policy result: accept

... but failes if I send it with
swaks --from=postmaster@??? --to=xxxxxxx@??? --server
zidmx1.univie.ac.at --data=dkimtest_signed.eml
with
Nov 27 14:54:00 ray exim[29036]: 1a2JTM-0007YK-BR DKIM: d=sproing.at s=rev1
c=relaxed/simple a=rsa-sha1 [verification failed - body hash mismatch (body
probably modified in transit)]

For signing I used
/usr/share/doc/perl-Mail-DKIM/dkimsign.pl --method=relaxed --selector=rev1
<dkimtest.eml
