With this option enabled, SpamSieve will never predict a message to be spam if its sender’s e-mail address is in the Contacts (previously Address Book) application.
You can add addresses to the system address book using the Contacts or Address Book application (located in the /Applications folder), or directly from an e-mail program that supports the system address book.
If spam messages get through to your inbox because they are sent from addresses in your address book, you can either uncheck Use macOS Contacts or see the Catch spam sent from my own addresses section.
Access to Your Contacts
The first time you use SpamSieve to filter messages, it will ask for permission to access your contacts. You can change the access setting by opening System Settings, going to the Privacy & Security pane, clicking on the Privacy tab, clicking on Contacts in the list, and checking or unchecking SpamSieve.app. (Please note that the applications in the list are not sorted alphabetically.)
Repeated Access Prompts
If the system keeps asking you for permission to access your contacts and does not remember this between launches:
You may need to reset the privacy database by entering this command in Terminal:
tccutil reset AddressBook

Mail Client Contacts
Outlook and Entourage users may prefer to use Microsoft’s address book as an allowlist instead of Apple’s. This is described in the Use Outlook/Entourage contacts section.
PowerMail users should be sure to enable the option to use Apple’s address book.
