I believe they misspelled "v=spf1 -all"
Why would a spammer purposely use a SPF record that states that no
email is sent?
That seems like it would be the exact opposite of the very thing they
want to do.
Is this some sort of technique to identify / harvest receiving domains
that run SPF filters to exclude from future spam runs?
I have my reservations that the spammer is the same that's listing the
domain for sale or running the DNS based on what I've seen
semi-recently.
