If you rate-limit 2 million compromised machines to 20 msgs/day each,
there's only  400 million spams.  Total.

IF you can rate-limit them across the whole Internet, If you limit 2 million machines to 20 msgs/day per mail server you are back up to your 10 Billion msgs/day mark. This is where DCC or other distributed checksum systems come into play.
