From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  whitelist n. The opposite of a blacklist. That is, instead of being an
     explicit list of people who are banned, it's an explicit list of people
     who are to be admitted. Hackers use this especially of lists of email
     addresses that are explicitly enabled to get past strict anti-spam
     filters.
