Does CLASSMATE.COM have a redundant SPF record?:

"v=spf1 mx ptr include:classmates.com -all"
Whats the point here?
The point is to cause infinite recursion, and thereby cause mail to be
rejected (provided client rejects on resource limit exceptions).
Most implementations will give SPF pass for legit mail. The infinite
recursion will only show up when the mail is from a spammer. A very
unfriendly to receiver policy.
