AUBnet SPAM Management Guide
for Outlook Express

  1. How to automatically move *CNS-Detected SPAM* messages to the "Junk E-Mail" folder?

    Email messages that come from the Internet via AUBnet central mail hubs will be scanned by an anti-spam filtering system (SpamAssassin). The filters work by looking for specific characteristics, and assigning a positive or negative 'score' value to each one encountered. At the end, a message's total score is compared to a threshold value. If the score is above a certain level, the message will be classified as spam and will be marked with "X-CNS-Detected-SPAM" signature in the message header and *CNS-Detected SPAM* in the subject before being delivered to the recipient Inbox.

    You can set up a simple 'rule' in Outlook to automatically move on receipt all *CNS-Detected SPAM* messages to a "Junk E-mail" folder. You will then be able to check that folder for 'false spam' before deleting all the spam messages.

    To filter all *CNS-Detected SPAM* messages and move them to the "Junk E-Mail" folder do the following:

    1. Start Outlook Express.
    2. click on 'Tools' from the menu bar, then choose  'Message Rules' and click on 'Mail'.
    3. Click on 'New' to start a new mail rule.
    4. Under 'Select the conditions for your rule' check the box next to 'where the subject line contains specific words'.
    5. Under 'Select the actions for your rule' check the box next to 'Move it to the specified folder'.
    6. Under 'Rule description' click on the first underlined blue value to edit it.
    7. Type Type in: *CNS-Detected SPAM* (with stars) in the empty field and click on 'ADD' then 'OK'.
    8. Under 'Rule description' click on the second underlined blue value to edit it.
    9. Click on 'New Folder' to create a new folder.
    10. Type ' Junk E-Mail ' under Folder Name and click on 'OK' then 'OK' again.
    11. Under name of the rule type "X-CNS-Detected-SPAM".
    12. Click on 'OK' and once again click on 'OK' to close the message rules window.

     

    The rule will start sending all new messages marked with "X-CNS-Detected-SPAM" to the "Junk E-Mail" folder.

    Notice: The rule is set to trap "X-CNS-Detected-SPAM" in the message header rather than trapping '* CNS-Detected SPAM*' in the subject. This is deliberate to allow the recipient to reply to and forward marked spam messages. If instead of that the filter was set to trap '*CNS-Detected SPAM*' from the message subject, replies and forwards would be trapped and moved into the spam "Junk E-Mail" folder.

    You can test the filter and move existing *CNS-Detected-SPAM* spam messages from your Inbox to the "Junk E-Mail" folder, by doing the following:

    1. click on 'Tools' from the menu bar, then choose  'Message Rules' and click on 'Mail'. 
    2. Ensure that your "X-CNS-Detected-SPAM" rule is checked.
    3. click on the 'Apply now' button.
    4. select the "X-CNS-Detected-SPAM" rule.
    5. click on the 'Apply now' button.
    6. when its finished - click 'Close' button then OK.

    The marked spam messages should be moved to the "Junk E-Mail" folder.

     

  2. Managing the "Junk E-Mail" folder

    Although CNS carefully tuned SpamAssassin to detect Spam while allowing genuine messages through, occasionally it may wrongly mark a genuine message as Spam. Messages marked as Spam that are not Spam are called 'False Positive' or 'False Spam'.

    You can report 'False Spam' to a special address false-spam@aub.edu.lb where the messages will be checked and added to a 'White List'. CNS will exercise due efforts to process the request within 2 working days and will notify the requester accordingly.

    You can recover 'False Spam' messages and report them to CNS to be added to the 'White List' by doing the following:
    1. Open your "Junk E-Mail" folder.
    2. Check through the messages for false spam messages.

      If you identify a 'False Spam' message
      1. Choose 'File' then 'Save as' option.
      2. Drop the 'Save as type' list and choose the 'Mail (*eml)' format.
      3. Click on 'Desktop' then the 'Save' option.

      To report a 'False Spam' message
      1. Start a new Outlook email message
      2. In the 'To' line type: false-spam@aub.edu.lb
      3. In the 'Subject' line type: reporting false spam
      4. Attach the message from the desktop.
      5. Write a covering note then send it.

      To recover a 'False Spam' message
      1. Right click on the message from the desktop.
      2. Choose 'open with' option and then choose Notepad.
      3. Edit the subject lines of the 'False Spam' to remove the '*CNS-Detected SPAM*' text.
      4. Save the edited message
      5. Drag the recovered messages to your inbox.

    You can delete SPAM messages from the "Junk E-Mail" folder by doing the following:
    **Check your messages to make sure that they are all really spam**

    1. Highlight all messages
    2. Press delete.

     

  3. How to add a personalized mail filter?

    To add a filter for .V.I.A.G.R.A. and move the messages to the "Junk E-Mail" folder do the following:

    1. click on 'Tools' from the menu bar, then choose  'Message Rules' and click on 'Mail'.
    2. Click on 'New' to start a new mail rule.
    3. Under ' Select the conditions for your rule' check the box next to 'where the subject line contains specific words'.
    4. Under 'Select the actions for your rule' check the box next to 'Move it to the specified folder'.
    5. Under 'Rule description' click on the first underlined blue value to edit it.
    6. Type Type in: .V.I.A.G.R.A. in the empty field and click on 'ADD' then 'OK'.
    7. Under 'Rule description' click on the second underlined blue value to edit it.
    8. Click on 'New Folder' to create a new folder.
    9. Type 'Junk E-Mail' under Folder Name and click on 'OK'
    10. Under name of the rule type "X-CNS-Detected-SPAM".
    11. Click on 'OK' and once again click on 'OK' to close the message rules window.

    The rule will start sending all new messages with .V.I.A.G.R.A. to the "Junk E-Mail" folder.

    You can be creative and develop quite complex filters and apply them to your inbox.
