Lets say that Joe Jobs has an SPF record of: "v=spf1 mx ptr
ip4:69.0.0.0/7 -all"
He could even use: "v=spf1 +all"
This is a valid record, and since he is coming from: 69.87.x.x it is
acceptable. But now I find out he is a spammer. I can't block
69.0.0.0/7 so now I am stuck denying specific IP's again.
You block his domain name, rather than his IP. This bring the block list to
a higher conceptual level.
