X-Spam-Flag filter
An X-Spam-Flag filter will catch only messages whose hits percentage meets or exceeds the 50% threshhold currently used by NC State. It will function only when the X-Spam-Flag header has a value of YES. Before you construct a spam filter, be sure to set up a spam folder in the Inbox of your e-mail client so that you can retrieve any legitimate messages caught by the filter.
NOTE: If you have already set up this type of filter for the SpamAssassin software previously used at NC State, you do not need to add a new one for PureMessage.

To construct a spam filter based on the PureMessage X-Spam-Flag header:

1. Open Pine.
2. Type s for Setup.
3. Type r for Rules.
4. Type f for Filters.
5. Type a for Add.
6. Type c for Change.
7. Give the filter a name; e.g., spamflag.
8. Scroll down the list, highlight Add Extra Headers and press the Return key.
9. Type X-Spam-Flag and press the Return key.
10. Type c for Change.
11. Type YES.
12. Press the Return key to set the value.
13. Scroll down to the Actions section.
14. Under Filter Action, highlight Move. Press the Return key.
15. Go down one line and press the Return key.
16. Type the name of your spam folder and press the Return key.
17. Type e to exit Setup.
18. Type y to commit the changes.
19. Type e to exit Setup again.
20. Type y again to commit the changes.

X-Spam-Level filter
An X-Spam-Level filter can be used to catch messages whose hits percentage is less than the 50% threshhold. You might want to create one if you feel that 50% is too high (doesn't catch enough spam). If you choose a threshhold that is not a multiple of 10 (e.g., 45%), you will need to create two of these filters instead of one. Before you construct a spam filter, be sure to set up a spam folder in the Inbox of your e-mail client so that you can retrieve any legitimate messages caught by the filter.
WARNING: Be very careful if you create an X-Spam-Level filter. The lower the hits percentage you choose for filtering, the more likely you will mistakenly catch legitimate mail and send it to your spam folder.

To construct a spam filter based on the PureMessage X-Spam-Level header:

1. Open Pine.
2. Type s for Setup.
3. Type r for Rules.
4. Type f for Filters.
5. Type a for Add.
6. Type c for Change.
7. Give the filter a name, e.g., spamlevel.
8. Scroll down the list, highlight Add Extra Headers and press the Return key.
9. Type: X-Spam-Level and press the Return key.
10. Type c for Change.
11. Type in your chosen hits percentage using the letters X and/or I:
    • If your percentage is a multiple of ten, type a number of X's equal to the tens digit of the percentage.
      For example, for 60%, you would type 6 X's (upper case):
      XXXXXX
    • If your percentage is not a multiple of ten, type in a number of X's equal to the tens digit followed by a number of I's equal to the ones digit.
      For example, for 65%, you would type 6 X's and 5 I's (upper case):
      XXXXXXIIIII
      NOTE: In this case, you will need to create a secondary filter (see below).
12. Scroll down to the Actions section.
13. Under Filter Action, highlight Move. Press the Return key.
14. Go down one line and press the Return key.
15. Type the name of your spam folder and press the Return key.
16. Type e to Exit Setup,
17. Type y to commit the changes.
18. Type e to Exit Setup again.
19. Type y again to commit the changes.

If your hits percentage is not a multiple of 10, you will need to create a secondary filter:

1. Open Pine.
2. Type s for Setup.
3. Type r for Rules.
4. Type f for Filters.
5. Type a for Add.
6. Type c for Change.
7. Give the rule a name different from the one above, e.g., spamlevel2.
8. Scroll down the list, highlight Add Extra Headers and press the Return key.
9. Type: X-Spam-Level and press the Return key.
10. Type c for Change.
11. Type in a number of X's equal to one more than the tens digit of your chosen hits percentage.
    For example, for 65%, you would type 7 X's (upper case):
    XXXXXXX
12. Scroll down to the Actions section.
13. Under Filter Action, highlight Move. Press the Return key.
14. Go down one line and press the Return key.
15. Type the name of your spam folder and press the Return key.
16. Type e to Exit Setup.
17. Type y to commit the changes.
18. Type e to Exit Setup again.
19. Type y again to commit the changes.

X-Virus-Detected filter
By using an X-Virus-Detected filter and creating a virus folder in the Inbox of your e-mail client, you can retrieve legitimate messages that arrived with virus-laden attachments that were later removed by PureMessage. Be sure to set up your virus folder before you construct a virus filter.

1. Open Pine.
2. Type s for Setup.
