No, you misunderstand. (At least with IPv4) Reputation ~= IP. The goal
is 1 client = (at least) 1 IP. Reputation DOES take time to build up,
and the best way to build it up is by sending relevant, permissioned
newsletters from an IP that is used by only ONE client. We agree, this
is how it should be. But lots of clients = lots of IPs...
But this is *WAY* OT...
