Interesting, thanks.  Do you reject PermError ?  Your table
says "unable to parse ip4:12.196.50.0/0", parsing this should
be not the real issue... ;-)
                            Bye, Frank


Well 12.196.50.0/0 is well quite incorrect and well what should I do?


For the verification tool, I would give a Warning rather than an
error.  Several of the other validation tools do likewise, as does
libspf2.

For example you could also give a warning if the domain doesn't exist
for the a: and mx: mechanism, or if no A records can be found with
those mechanisms.  In particular, things like a:1.2.3.4 are fairly
common, but the spec now requires that you reject it because "4" is
not a valid TLD.  Instead, you could also give the helpful hint that
ip4:1.2.3.4 is probably what they want.  Likewise, the use of ipv4:
instead of ip4: could be explained better than simply saying that
"ipv4 is an unknown mechanism".
