Spammers hapless fate = ISP toil and sweat

This is a bit off topic, but I disagree.  If you're as unscrupulous as these
guys, getting new IP numbers is as easy as this:

: interface Ethernet0
:  ip address 219.1.1.1 255.255.0.0
:
: router bgp xxxx
:  network 219.1.0.0 netmask 255.255.0.0
:
: ip route 219.1.0.0 255.255.0.0 Null0 254

Hey presto:  you've just got a /16 block which will probably get routed to
most Internet sites.  If the block doesn't get routed everywhere, it's not
the end of the world.  Hey, it's only spam -- 90% saturation is almost as
good as 100%.

This is one reason why address-based inbound filtering of customer BGP
announcements is critically important.

Mario, I like your solution, but does it scan individual email messages, or
just mail logs?  If it's the former, does it chew system resources?
