How do I sort tagged messages in Apple Mail?
1. Open Mail.
2. Go to Mail>Preferences>Rules.
3. Select Add Rule.
4. Name the rule as Spam and use the options in the Rules dialog box to configure the rule; use the triangles to see the choices. The rule should go something like this:
If any of the following conditions are met: Subject Contains SPAM
Perform the following actions: Move Message to mailbox: Trash
**Selecting the folder "Trash" will delete the message automatically once you exit out of Mail. You'll need to create a folder such as "Spam" and use that in place of the folder "Trash" if you want the ability to review and delete the message manually.
5. Click OK to apply the rule.
