How to white list an email address

What is email whitelisting?

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 Spam or 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 an email blocking program aka spam filter keeps a whitelist, mail from the listed e-mail addresses, domains, and/or IP address will always be allowed and will be shown in Inbox.

Some spam filters delete suspected junk e-mail messages straightaway, but others allow the user to place them in a quarantined inbox. Periodically, the quarantined messages are observed to see if any of them are legitimate messages. This option is used by some Web-based e-mail clients in place of, or in addition to, a whitelist.
