perhaps we need to specify in -protocol that "ipv4" and

I've already done this in my Python implementation.  I've heard and
understood the arguments that this is a bad thing, because then the
publisher will never know they screwed up.  However, I block a few percent
more spam by accepting SPF records with ipv4 and pretending it said ip4
instead of returning "unknown" as required by the standard.

Based on observed incorrect SPF records, I have installed the following
synonyms:

ip,ipv4 = ip4
prt     = ptr

While I haven't seen any yet, I might as well add

ipv6    = ip6

for good measure.
