A standalone firewall-box-thingy for your broadband is only like $15 or
so today. Let's lobby the lawmakers to make it mandatory to ship one of
those if you ship a box with windows on it to a customer :-) Or at least
ship the recovery CDs with SP2 preinstalled (which has a firewall that's
definitlyi enough to deal with *that* threat pre-installed).
But. That's not really what this thread is about. I thought it was
reasonably well established that even *IF* SPF worked the way it's
supposed to (I'm not getting into that discussion, this is clearly the
wrong forum for that), it's not appropriate for the postgresql.org
domain specifically because we have several users relaying through a
whole set of different MXes.

Hey, maybe we can set up a version of PostgreSQL that can run
distributed across one of these zombie nets? Talk about processing power
for your queries. Maybe I should speak to the bizgres guys about that.
