Thanks.  That's a good start.  Now, how will I know when a domain has
an SPF record to validate upon?  What do they look like?

When I do this on your domain, I see a TXT record that begins
> v=spf1
and has what appears to be two SMTP system addresses (a:), and an
~all.

Would I be correct to read it as,
