Some of the work the python.org postmaster (Greg Ward) is doing
involves examining and rejecting messages during the SMTP dialog.  The
trick is to force them to do more work to deliver their spam, upping
the costs of the sending host just enough for it to be not worth it.
Unfortunately, I suspect our own costs will go up faster than theirs
so we'll likely lose this battle too.  But IMO, anything that isn't
economics based will fail.

Yup, but on the other side of the coin, they're getting sued and
losing for not verifying their opt-in lists.  But none of that matters
either given the global nature of things.

    JWB> Ah, well...we'll see how it goes.
