Because it looked easier than Mail::SPF, when I checked CPAN for SPF 
modules, and works for my needs. You need a "SPF server" object, query the 
result, but the record is in the original request.

It also looks heavier in regards of ressources.

This is actually a point to consider, because I'm also interested in "Does 
somebody know of a SPF implementation that only checks for "null SPF 
entries", aka "v=spf1 -all"? But does support, probably, TXT/SPF RRs and 
v=spf2.0 as well?"

Anyway, can I simplify Mail::SPF's checks to just take a look after null 
entries? Probably the "max_*" settings, let's see, ... .
