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
That's a good idea, should be put into the specs to accept all 3.

prt   = ptr
That's not a good idea, its clearly a typo, and prohibits the use of prt for 
something real in the
future.


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

ipv6  = ip6

for good measure.

Also a good idea
