If that were true, I wouldn't be seeing millions of paypal, linkedin,
et. al. impersonations a day.  But I do.

Validation is so irrelevant that the spammers impersonate sites when
it's clearly unnecessary.  They use their facebook impersonation
templates to send out pill spam for crissakes.  If validation was making
a difference, the ROI would suffer.  I can only guess it isn't.

The reality is that you don't have to forge the From/sender/helo et. al.
to successfully impersonate any domain.  Especially with the mail
readers oh-so-carefully _not_ showing you the actual email address.

Most spoofers are already bypassing validation.  So why would it matter
to them whether the mailbox provider is validating or not?
