They're not *exactly* the same idea.  Razor's aim is to catch known spam
(I assume the same is true of Pyzor, though I haven't used it).  DCC's
job is to tell you when a particular message has been received by many
recipients.  It doesn't distinguish between solicited and unsolicited
bulk mail, so you need to be careful about whitelisting or risk tagging
legitimate mailing list traffic.
