SPFv1 can support HELO checking, if you are willing to put up with

verification.
how can do you that ?
- publish a spf record for ols.es with ~all
- allow postmaster(_at_)ols(_dot_)es to send mail
- prohibit ANYBODY to use ols.es in the helo
Another quick followup question.
Do you actually send mail from postmaster(_at_)ols(_dot_)es? How often?
Would you be willing to alter the mail being send from postmaster(_at_)ols(_dot_)es so
that it is From: postmaster(_at_)ols(_dot_)es in the headers but the return address is
"postmaster-return(_at_)ols(_dot_)es" or even "postmaster(_at_)postmaster(_dot_)ols(_dot_)es"?
In other words, are you searching for a pragmatic (i.e. working) solution,
or is this just about theory?
