if you wanted to go the mad route of defining legit sending ip's via their
helo is
"v=spf1 include:%{h4r}.smtp.example.com -all"
That doesn't validate the HELO name.
and ensure the spf for each xx.smtp.example.com is
"v=spf1 A -all"
You are confusing the HELO and MAIL FROM identities.
as i have repeatedly mentioned this will not get you round anyones checking
for valid ptr {as its unconnected to spf} {as far as the spf ptr: method i
That is a fair point. I am not pushing a helo mechanism anymore, just
reponding to comments that seem to miss the function. It would still
be a "nice to have" in addition to PTR, but if you don't like PTR,
you won't like HELO either as an SPF3 mechanism (since it is just
a PTR delivered via SMTP HELO).
