Preventing domain forgery will have no effect on anything
Excuse me ??? If _you_ would check _my_ SPF record, I will not
receive _your_ out-of-office reply because _someone_else_ sent mail
to _you_ using _my_ address.
Because you are being stubborn, _I_ have to suffer.
We can already associate an IP address with a domain via MX and A records.
However, these checks aren't valid except to show that domain //can//
receive email. We already know through experience that many more servers
might validly send email from that domain.
Indeed. MX or A define what addresses will _receive_ email. And SPF
defines what addresses are allowed to _send_ email. Excellent point,
but in favour of the opposite of what you are trying to defend.
