OpenDKIM canonicalization changed to relaxed for mail headers

Browse Source 
Because Mailman reformats headers it breaks DKIM signatures. SPF also does
not apply in mailing lists. This together causes DMARC to fail and mark the
email as invalid. This fixes DKIM signatures for Mailman-based mailing lists
and makes sure DMARC test is passed.
