The SPF Milter allows you to define a default SPF record
to be used when the site does not have a published record.

It beats trying to roll your own solution, and reduces
the chances of false positives since published SPF records
reflect the _actual_policy_ of the domains publishing them,
and the default policy you set reflects your policy for the
sites that can't be bothered to tell you theirs.
