An e-mail whitelist is a list of contacts that the user deems are acceptable to receive email from and should not be sent to the trash folder.
Spam filters that come with e-mail clients have both whitelists and blacklists of senders and keywords to look for in e-mails. If a spam filter keeps a whitelist, mail from the listed e-mail addresses, domains, and/or IP address will always be allowed.
Some internet service providers have whitelists that they use to filter e-mail to be delivered to their customers.
If a whitelist is exclusive, only e-mail from those on the whitelist will get through. If it is not exclusive, it prevents e-mail from being deleted or sent to the junk mail folder by the spam filter. Usually, only end-users would set a spam filter to delete all e-mails from sources not on the whitelist, not internet service providers or e-mail services.
Using whitelists and blacklists can assist in blocking unwanted messages and allowing wanted messages to get through, but they are not perfect. E-mail whitelists are used to reduce the incidence of false positives, often based on the assumption that most legitimate mail will be from a relatively small and fixed set of senders. To block a high percentage of spam, e-mail filters have to be continuously updated as e-mail spam senders create new email addresses to e-mail from or new keywords to use in their e-mail which allows the e-mail to slip through.
