3) One generally never publishes records about HELO at the same
domain name as MAIL FROM or PRA. Hence they'd never share a record.
That's strange. If you publish a SPF record for example.com, surely
mail.example.com (the name you announce in HELO) has a SPF record,
too? (Otherwise, it is trivial to defeat your SPF record, the method
is left as an exercice.)
