That's right. They joe-job my domain instead, and I get over a
thousand bogus bounces a day. If SPF deployment does nothing but stop
that (which it can), it's a win.
SPF will do very little to eliminate the bad effects of joe jobs. It
requires too much co-operation from all over the Internet, most of which
doesn't care enough. If you want to reliably eliminate backscatter,
use BATV which requires no help from anyone else.
Zombie nets are a different problem to be solved with different methods.
It's reasonably possible to identify zombie networks with intrusion
detection techniques, identifying machines that emit viruses and run
spamware. They can then be blocked.

VEERING SOUTHEAST 3. THUNDERY SHOWERS LATER. GOOD, BECOMING MODERATE OR POOR
WITH FOG PATCHES IN SOUTH. SLIGHT, OCCASIONALLY MODERATE AT FIRST.
