You really want to keep such whitelists in DCC clients or greylist
servers.  The straight DCC server whitelist was a bad idea based my
very shallow thinking.

There's nothing wrong with that, except that I fear that it is hopeless.

One person's interesting and purely solicited newsletter becomes another
person's very obnoxious spam after a "courtesy subscription."

Another reason is that I suspect that there a million legitimate
newsletters and other streams of ordinary mail involving than 100
recipients each.

A third, paradoxial problem is that the most popular and most obviously
bulk streams of legitimate mail are least likely to appear to be bulk
to the DCC.  A mailing list with 1,000,000 subscribers will have low
DCC counts if most DCC clients whitelist it.  Common or popular whitelist
entries are the entries you need least.

Please don't misunderstand me as saying you shouldn't try.
The worst likely concrete problems are disagreements about the
legitimacy of individuals streams of bulk mail.
