(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.
