Senders change their IPs. If they have an SPF record, this is transparent.
For important senders with no SPF record, I can create a local one manually
to positively identify them.
How many of these records do you maintain? How much time does it take?
Currently 90. Very little time. Most senders are handled by the
default best guess - "v=spf1 a/24 mx/24 ptr". The local records are treated as
alternate "best guess" policies. For example:
$ORIGIN _spf.bmsi.com.
fedoraproject.org IN TXT "v=spf1 ptr:redhat.com ?all"
What is the problem with these senders? What will it take to motivate them?
