Set up Central Spam Filtering

In order to help you manage the Spam that gets directed to your email account, all email bound for Dartmouth passes through SpamAssasin. SpamAssassin uses a rating system similar to the Star rating system for hotels. Instead of Stars, it uses lower case "s"s. The more "s"s SpamAssassin awards, the more likely the email is Spam. It attaches these "s"s to the email before it gets to your mailbox.

In order for the Spam to be caught, you need Create/Edit a "Rule" in BWA.  Then, when it gets to your mailbox, the rule evaluates how many "s"s have been awarded and compares that to the number of "s"s that you have determined email has to have in order for it to qualify as Spam. If the number of "s"s awarded by SpamAssassin is greater than or equal to the number of "s" in your Spam Rule, it will direct the email to the Junk Email folder, otherwise, the email will end up in your Inbox.

For this to be most effective, you will create/edit a Spam Rule and turn OFF local spam settings in the application that you use to access your e-mail: Outlook 2010, Outlook 2011, Outlook 2013, Apple Mail, Thunderbird, or Entourage 2008 Web Access Edition.

    If the rule !!DartDM Spam Rule: do not edit by hand!! already exists in this list then there is no need to move forward with these steps, just make sure that it is enabled by placing a check in the “On” box in the left column and proceed to edit the rule if necessary.
  6. Click the “+” icon (New).
  7. Click “Create a New rule for arriving messages”.
  8. Name the rule: !!DartDM Spam Rule: do not edit by hand!!
  9. Click More Options…
  10. In the drop down box beginning with “When the message arrives” choose: It includes these words… in the message header…
  11. Type in: X-MailScanner-SpamScore: sss
    Type between 1 to 15 lower case “s”s (replacing the 3 you see in this example) depending on the desired strength of you spam filtering (1 “s” = lots of mail will be considered Spam. 15 “s”s = Virtually no email will be considered Spam). Be sure to leave a single space between the colon “:” and the first lower case “s” and no spaces between each lower case “s”.
  12. Click the “+” icon (add).
  13. Click OK.
  14. In the drop down box labeled with “Do the following” choose: Move, copy or delete…Move the message to folder…
  15. Select your Junk Email folder from the list.

How to Edit a Spam Rule

  1. Use your browser and log into BWA: https://bwa.dartmouth.edu.
  2. In the upper right corner click the Gear Icon (Settings).
  3. Click Options.
  4. Click Organize email.
  5. Click Inbox Rules.
  6. In this list of Inbox Rules click the rule named !!DartDM Spam Rule: do not edit by hand!!. Contrary to the warning you will edit this rule. (If you don’t see the rule in the list, you will need to create one. See Creating your Spam Rule.)
  7. Click the Pencil icon to edit the rule.
  8. To the right of the box that indicates “It includes these words in the message header…” Click the link that begins with ‘X-MailScanner-SpamScore:’
  9. Click the Pencil icon and increase or decrease the number of lower case "s"s that appear. The more "s"s that you include in the filter, the more spam you are likely to see in your inbox. The fewer “s”s that you include the more likely it is for something that is not spam to end up in your Junk email folder. We typically recommend three s's.
  10. Click OK.
  11. Click Save.
  12. If you see a warning message, click OK.
