(n.) In Internet terminology, a generic name for a list of e-mail addresses or IP addresses that are considered to be spam free. Whitelists are used frequently with e-mail applications to allow users to compile lists of senders they wish to receive e-mail from. This list overrides any blacklists and spam filters, and allows the e-mails to be delivered to the users inbox instead of filtered out as spam.

(v.) To place an e-mail address or an IP address on a list of accepted senders.

Whitelist may also be seen written as white list or white-list. Contrast with blacklist.

AOL - Creating Whitelists
AOL is creating a "whitelist" of e-mail marketing companies that agree to abide by its policies, and it will allow them to send graphic-laden emails directly to AOL subscribers.

Protecting Exchange Against Spam
One way of automatically creating a whitelist is examining all outgoing mail. Recipients of mail sent from internal users are considered "safe" senders. This can be problematic if an internal machine starts sending e-mails because of a virus. Use this option only if you have anti-viruses deployed internally (as you should) and latest service packs are installed on the Outlook clients.

This provides information on the evolution of spam, and includes a brief section on creating a whitelist.
