To whom it may concern...

I've run a little test whether Swiss ISPs use SPF or not and it turned out that very few have actually implemented it (actually, I found not a single one). Is there a reason for that? It's a very simple implementation and it could prevent a lot of damage like the most recent one after Sober.Q.

SPF is broken by design.

I would suggest ISPs should implement SPF quickly and talk to their customers about it. (See http://spf.pobox.com/ for further information.)

How about you start with your domain and your users first and then report back how it went and what problems you encountered? Lead us the way!
