The most common use of email filters is to remove unsolicited commercial e-mail (spam) from your Inbox. By default all mailboxes are pre-loaded with a spam filter which delivers all emails our servers determine as spam to the Spam folder instead of the Inbox.
To manage your email filters on the servers, first log into your webmail. Once logged in, click the "filters" link that appears at the right end of the menu. A list of current filters is shown.
Adding a filter
Click on the "Add a New Rule" button and follow through the wizard. As an example, here is how to create a spam filter moving all emails to a folder called "Spam":
Choose "Header Match" and click "Move on to Step 2"
Choose the "X-DSPAM-Result" from the header list and type "Spam" in the text box.
Choose "Move message into" - if you have created a folder already choose it from the existing folder list. If not choose "a new folder" and name it "Spam" as a subfolder of "INBOX". Tick the checkbox beside the stop sign at the bottom, and click "Move on to step 4."
You will be presented with the rule you just created. Check that it is correct and click "Finished". The rule is not yet active, you need to click "Save Changes" and then the rule is saved.
Changing a filter
Click on the edit icon on the right side of the filter you wish to change. The details of the filter are shown and can be modified. Click "Apply Changes" once you've made your changes and then click "Save Changes" to get them saved to the server.
deleting a filter
Click on the delete icon on the right side of the filter you no longer want. To make the delete permanent you need to click "Save Changes".
