They're *still* easy to spot by backscatter levels, probably because (a) a lot of people still have that switch set to "on" (b) some people still switch it to "on" (c) Barracuda's engineers apparently think that using SPF stops backscatter -- and it most emphatically does not. Reject gooooood, bounce baaaaaaad. [1] Now whether there are *other* ways to spot them: I don't know. But there are some very sharp people at Spamhaus, and it would not surprise me if they knew. ---Rsk [1] Unless you are bouncing to an authenticated/internal user.
