We have considered this idea in the past, and chosen not to
proceed for a number of reasons. The strongest reasons are:
if we did this we would use an underscore ---
"_spf.domain.com" and enough people believe that underscores
are not permitted in DNS to cause significant friction.
if we did this, it would be difficult to support wildcard
subdomains.
