Lets say that Joe Jobs has an SPF record of: "v=spf1 mx ptr
ip4:69.0.0.0/7 -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.

Don't deny specific IP's; deny messages that claim to come from
JoeJobs.com.

Internet commerce will never really take off until you can buy something
online without getting spammed by the vendor.
