_And_, I screwed this up -- having arrogantly not bothered to
double-check SPF TXT RR syntax before writing the RHS string, and
instead doing it from memory.  Correct version:

              IN      TXT     "v=spf1 ip4:198.144.195.186 -all"

Note (correct) 'ip4', vice (incorrect) 'ipv4'.

That'll teach me to skip the all-important 'verify your work' step.
Fortunately, the RR wasn't incorrect (invalid syntax) for very long.


Useful tool:  Send an e-mail to check-auth@verifier.port25.com and you
will receive a reply containing the results of an SPF check.

The similar tool that used to be available at spf-test@openspf.net has
been discontinued.
