I guess I've never really seen the point of publishing a SPF record if it ends in ~all. What are people supposed to do with that info?
Spamassassin assigns it a score of 0.6 but that is low enough it really doesn't have much since it doesn't assign any negative points for SPF_PASS.

I certainly understand that you may not be able to lock down your domain. We don't even try for customers for instance. However, if you can't, I guess I don't really see what good publishing a SPF record is if you tell people not to enforce it.
