No, wait. Didn't I say it has to get an SPF "pass" to get usable?
I must have considered it implied... my bad.
It doesn't help.

spammerdomain.com IN TXT "v=spf1 ip4:0/0 -all"
That's not quite how helo authentication works. When they say "helo
wmail.tana.it" the server looks up wmail.tana.it.
wmail.tana.it. IN TXT "v=spf1 redirect=tana.it"
tana.it. IN TXT "v=spf1 +ip4:62.94.243.226 -all"
They won't get a "pass" unless they are using that ip4.
