How to do it |

Determine your preferred minimum spam "score." |
- UCSD's spam filtering system assigns each message a score, representing the probability that the message in question is spam.
- A message is tagged as spam if it receives a score of 5.0 or above, represented in the mail message in the X-Spam-Level header by the number of asterisks (*).
- Choosing a lower value will result in a greater volume of spam in your spam folder and also increase the likelihood of a legitimate mail message being sorted as spam.
- To determine the level at which you feel comfortable filtering, examine the assigned score on a variety of messages in your inbox.
- View the mail headers of your e-mail by highlighting a message.
- Click the View pull-down menu, and select Show All Headers. The spam score usually appears near the bottom.

Pay attention to filtered spam. |
- Incoming e-mail that appears to be spam will automatically be moved to the new folder you created.
- It's possible for legitimate e-mail to be marked as spam. Periodically check the contents of the Spam folder to ensure that this has not occurred before deleting its contents.

Turn off "Junk Mail" filtering in Mac OS X 2.x and later (optional). |
- Apple has included a feature that heuristically filters spam. This means you train it with what you think is spam, and eventually it will "know you well enough" to be able to filter the spam into a separate mailbox.
- Some users find this method provides too many "false positives" where legitimate mail is labeled as "junk." To turn this feature off:
- Select the Mail menu.
- Point to Junk Mail and choose Off.
