Just so there is no confusion... this is good news for SPF, not bad news.


Absolutely, completely agreed! I should have elaborated. As I have said in various public posts (elsewhere), if spammers want to tie themselves to their sites by authentication, that's a *good* thing. My points are that a) spammers will adopt whatever is out there, and in this instance b) spammers are stupid - by adopting what they *think* is an anti-spam protocol to help get their spam through, they are actually raising their hands and saying "here I am!"
