This is completely contrary to my experience.  Because I use shared MTAs, 
almost all e-mails I send have an SPF NEUTRAL (?) result.  In about a year 
and a half of doing this, I've had exactly 3 e-mail messages rejected (not 
disappeared by the way) and they were all the result of configuration errors 
on the distant end (2 of the 3 thanked me for pointing out their error).  As 
far as I know, I've had NONE disappear.

So, even if you start out with the premise the SSP is like SPF (I don't think 
that's right either), nothing that follows in the original e-mail is correct.
