When Pyspf get a PermError, it still attempts to get a "best guess" result
Another Permerror heuristic
by heuristically examining the SPF record. I just realized another simple
addition to its bag of heuristics. When the error is "two or more SPF
records (or TXT records), simply evaluated both, and if the results agree,
that is the best guess - a pretty confident guess at that. I would only
apply this for 2 records, since that would arise in practice when naively
updating SPF records.
In fact, this would be another tweak for SPFv3: only report PermError for
exactly 2 SPF records (v3 should not use TXT) when the results disagree.
If both records get the same result, that is an official result.
