Once you’re satisfied, go back and select the “Move to the Junk mailbox” setting again. My suggestion for Mail’s junk settings? Stick with the “Mark as junk mail, but leave it in my Inbox” under you start feeling comfortable with how Mail is marking suspected spam messages. On the following screen, you can review and tweak Mail’s junk filtering rules, from whether the sender of a message is in the Contacts app to which folder junk messages are sent to after they’re tagged. Click the “Perform custom actions” option under the “When junk mail arrives” tab, then click the Advanced button.

Launch the Mail client, click the Mail menu in the top-left corner of the screen, select Preferences, then click the Junk Mail tab.Let’s dive into Mail’s junk settings for more options.

Of course, the “Add to Contacts” trick won’t work all that well if you don’t even realize an important email message has been junked. Just click the address in the “To:” field of a junked email, then select “Add to Contacts.” Well, the quickest way to keep Mail from junking a specific non-spam message is by clicking the “Not Spam” button with the message and adding the sender to the Mac’s Contacts app.
