I control a number of inactive domains. They have proper DNS records, but
no A records nor MX records. Thus, they cannot receive mail, and many
MTAs might refuse to accept mail claiming to be from such domains, as
there are no valid return paths. I would like to publish the appropriate
spf records to indicate that they do not send mail.
Is it simply
IN TXT "spfv1 -all"?

OT: I don't think the term 'parked', which is pushed by some registrars,
is a good one, and am trying to find a better one, but that may just
be some irrational hypersensitivity on my part.
