Interesting  idea,  Matt.  Still  way  too much management compared to
SPF-compatibleformatting,though.   The   ability   to   append
._spf.example.com  to  SPF  queries,  or use the SPFDOMAINS text list,
would be a lot easier.

Scott,  any  thoughts  on my suggestion of an extended SPFDOMAINS test
type with which you could manually maintain SPF-formatted policies for
given domains, running the data through the existing SPF parser?
