Lately my customer and I have been getting innundated with spoofed emails that LOOK like they are coming from our domains but when checking the headers I am noticing two things.
One. The IP addresses are from outside our network
TWO. Sender has no reverse DNS
Is there a way to block senders who have no reverse dns setup?
