6.1.2 Utiliser le carnet d'adresses
With this option enabled, SpamSieve will never predict a message to be spam if its sender’s e-mail address is in the system address book.
You can add addresses to the system address book using the Address Book application (located in the /Applications folder), or directly from an e-mail client that supports the system address book.
Mailsmith and PowerMail users should be sure to enable the option to use Apple’s Address Book. Entourage users may prefer to use their address book as a whitelist instead of Apple’s. This is described in the Entourage section.
