4.2   Automatically Deleting Old Spam Messages

You can set your mail program to automatically delete old spam messages. However, if you do this, you should still review your spam messages to make sure that no good messages are deleted. Not only would you lose such messages if you don’t correct all the mistakes, but SpamSieve would also incorrectly learn that they are spam, leading to more mistakes in the future.

Apple Mail

We recommend Setting the Junk Mailbox in Apple Mail. Then:

• You can quickly delete all the messages in all the Junk mailboxes by using the Mailbox ‣ Erase Junk Mail menu command.
• You can set Mail to automatically delete old spam messages. Go to the Mailbox Behaviors (or Special Mailboxes) tab of the Mail’s Accounts settings and select a time interval for Erase junk messages (or Delete junk messages when). You’ll need to repeat this for each account.

Entourage

You can set Entourage so that when it quits it will delete all the spam messages that are older than 7 days (or whichever interval you choose):

1. Choose Tools ‣ Run Schedule ‣ Edit Schedules.
2. Click the New button to create a schedule.
3. Set the name of the schedule to Delete Old Spam, the When to On Quit, and the Action to Delete Junk Mail from Junk E-mail (On My Computer).
4. Click OK to close the dialog.
