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

spf records to indicate that they do not send mail.

IN TXT "spfv1 -all"?
Close - remove a 'v':
IN TXT "v=spf1 -all"
Do a
dig altavista.com TXT
to see another option.
