- 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 Eudora 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:
- Start Eudora.
- Click on 'Tools' from the toolbar, then on 'Filters' .
- Click on the 'New' at the bottom to create a new rule.
- Make sure that 'Incoming' checkbox
is selected.
- Select «Any Header» from the drop down list next to the
first'Header' field.
- Type in: X-CNS-Detected-SPAM
in the empty field next to 'contains'.
- Choose 'Transfer To' from the drop down list under Action.
- Click on IN field.
- Click on the 'New' field in the drop down list to create a
new mailbox.
- Type 'Junk E-Mail' as a name for the mailbox in the
white space and click on OK.
- Click on 'File' from toolbar click on 'Save' to save your filter and then click on 'Close' to
close it..
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 newly received *CNS-Detected-SPAM* spam messages to the "Junk E-Mail" folder, by doing the following:
- Send a new message with your email account in the TO field.
- Ensure that you type "X-CNS-Detected-SPAM" in the Subject
field.
- When you receive the message, open the Junk E-Mail mailbox and the
message should be automatically transferred to this location.
- 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:
- Open your 'Junk E-Mail' folder.
- Check through the messages for 'False Spam' messages.
If you identify a 'False Spam' message
- Choose 'File' then 'Save as' option.
- Click on 'Desktop' in the 'Save in' option.
3. Check the'Include headers'
checkbox and click on save.
To report a 'False Spam' message
- Start a new email message
- In the 'To' line type: false-spam@aub.edu.lb
- In the 'Subject' line type: reporting false spam
- Attach the file from the desktop.
- Write a covering note then send it.
To recover a 'False Spam' message
- Open the ' Junk E-Mail ' folder.
- Drag the required 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**
- Highlight all messages
- Press delete.
- 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:
- Click on 'Tools' from the toolbar, then on 'Filters'.
- Click on the 'New'at the bottom to create a new rule.
- Make sure that 'Incoming' checkbox
is selected.
- Select «Any Header» from the drop down list next tothe
first 'Header' 'field.
- Type in: V.I.A.G.R.A
in the empty field next to 'contains'.
- Choose 'Transfer To' from the drop down list under Action.
- Click on IN field.
- Click on the ' New ' field in the drop down list to create a
new mailbox.
- Type ' Junk E-Mail' as a name for the mailbox in the
white space and click on OK.
- Click on 'File' from toolbar
click on 'Save' to save your filter and then click on 'Close' to
close it..
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.
