Are these spams being sent from zombies?  If not, then we
possibly should not be listing them.  If they're sending from
their own mailservers then it's vastly more efficient to just
block their IPs at a low level, i.e., regular (local or global)

Regarding using SURBLs on headers, I guess I'd view that as
mission creep and somewhat away from our original focus of URI

Do any spam gangs put the URI domain on their headers when they
use zombies?  Seems to me they tend to forge everything except
the URI.
