Hi !!
Since it relates to SPF, perhaps we could add something in SPF like
HELLO to simply indicate that we are supporting some additional DNS TXT
records for confirmation of the sending SMTP/ESMTP server's HELO/EHLO.
but, there is no nedd to do that, if you want to split things, better
don't require any change to spf. A totally sepated protocol is good,
it will keep thing simple, any part will make just it's job, no
modification to spf is need and if you use the same syntax as for
spf records you could take profit of the current spf implementations,
as they will be able to support the new record with just a little
modification.
