Is it?  There are 5 million zombies, perhaps, but there are many *more* 
legitimate e-mail users.  At the very least, that allows us to get the 
"percentage of e-mail that is spam" down below the 50% mark that it 
passed many months ago.  Remember that spammers have to spread those 
zombies out among all their campaigns and targets.

Right now, each zombie can send tens or hundreds of messages a second.  
Reducing that to one or less per minute would, in itself, put a big 
damper on their operations.
