Would the SPF filter:
1.
first check the sending mail server against the MX records in the
specified sending domain DNS entry to see whether that mail server is in
the MX records.
No. Unless the domain owner told it with the "mx" mechanism.
2.
then check if an SPF TXT record exists in that domain DNS entry. And if
there is no SPF record, FAIL the email.
No. What to do when there is no SPF record is a local policy issue.
