DKIM, SPF, etc. are authentication technologies. They tell you
something about the origin of mail.
They can be helpful to whitelist mail from known people.
They don't help at all when you and whitelist mail from total
strangers.
> Any suggestions on what I could do to mitigate this?
Don't whitelist mail from total strangers.
