#Spamassassin whitelist how to

Whitelists are most commonly used to ensure that messages from important senders are not marked as spam, but they can also be used to change the spam threshold for recipients or enable recipients to effectively opt out of spam-tagging. SpamAssassin whitelists reduce the spam scores of messages when the sender or recipient appears on the whitelist. A related feature, autowhitelists, is covered in Chapter 4. It begins by examining the SpamAssassin directives for systemwide whitelisting and blacklisting, and then explores two different ways to manage user-specific lists.

#Spamassassin whitelist how to

This chapter discusses how to set up whitelists and blacklists. SpamAssassin also allows you to set up system-wide or user-specific lists of senders whose mail should be tagged as spam. You may know ahead of time that you don't want to receive mail from certain organizations or senders. On the other hand, you may regularly receive unwanted mail from a particular sender that doesn't get tagged reliably by SpamAssassin. SpamAssassin allows you to set up systemwide or user-specific lists of senders whose mail should not be considered spam, and (systemwide) lists of users who don't want their email filtered. You may even have users who don't like spam-filtering. You may want to be sure that SpamAssassin will never mistake email from an important user, client, vendor, or other sender for spam. Although SpamAssassin generally does a good job of avoiding false positives, you may find that some mail that you want to receive contains enough spamlike characteristics that SpamAssassin regularly tags them as spam.
