10 - Filtering Junk or Spam in iSchool Email Accounts
Our iSchool system administrator has kindly installed a program called Spam Assassin on the iSchool server. This program automatically scores all email that goes through the iSchool server, and regards anything with a score of 5.0 or above as spam or junk email. This allows you to set up manual filters which will utilize this score and appropriately remove unwanted junk mail from your inbox … no training wheels on Mozilla required!
1. First, you will need to view the full headers on your email messages – under View select Headers – all. You are looking for the SpamAssassin tag, and the score or “Spam Level.” More than 5 stars rate the message as spam or junk, and SpamAssassin “flags” the email as spam.
2. Next, we are going to create manual email filters which make use of this spam flag. Go to Tools and then Message Filters.
3. Click on New and a new message filter window will appear
4. Name your Filter Spam filter on ischool server (SpamAssassin)
5. Create a customized filter by clicking on the box that currently says Subject – scroll down to Customize. A “Customize Headers” window will appear. In the “New message header” box, enter the following phrase exactly: X-Spam-Flag. Click OK.
6. You are returned to the filter rules screen – once again, in the drop down box that currently displays “subject,” select the X-Spam-Filter you just created. In the middle box that reads display, select "is." And in the final box on the right, type in YES (all caps).
7. We want Mozilla to move messages it finds with this filter to a designated folder. In the lower portion of the window, find and check the box adjacent to Move to folder and in the drop down box, make sure that your ischool.utexas.edu account is selected. You can create a new folder by clicking the New Folder button and naming the folder “Spam” – in the drop down box, select to move it to a local folder, and inside that folder, place it in the junk folder (if one exists). You will be returned to the Record Filters window, and click on OK.
8. You are then returned to your Message Filters folder – make sure that the spam filter you just created is enabled. Additionally, click on the Filter Log button and enable Mozilla to log how it filters your email by checking the box at Enable filter log. Click OK
9. To run this filter, click on the Run Now button at the right.
10. To double check that your manual filter was able to filter only messages that are truly spam, look to the window at the left in your local folders. Find the spam folder just created, and view messages moved there to be certain that these messages are indeed spam.
