Public bug reported:
If DNS lookup of TXT records for a domain finds more than one v=DMARC1; record,
it checks them all for policy = reject or quarantine.
RFC 7849, Sec 6.6.3 item 5 says
5. If the remaining set contains multiple records or no records,
policy discovery terminates and DMARC processing is not applied
to this message.
Thus, if we find multiple records we should assume no DMARC policy for this
domain.
