The problem was that a medium to large sized ISP decided to use a
whitelist from a third party. After contacting the company that ran
the whitelist, it was determined that it would cost about X amount
per year to send email to members that used the particular ISP.
While it is (IMHO) perfectly acceptable for the recipient to
whitelist/blacklist and to block emails using a content filter, it is
totally inappropriate for a third party to do so. Only the recipient
should have the right to decide which emails (s)he wants to receive.
