The default settings provide a reasonable protection, better than the old SpamAssassin based mailfilter the university used before. Usually the settings do not need to be changed. But if you really want to, this is how.

  1. Login to SUNET Mailfilter at Click on Login using SWAMID.

  2. Find Uppsala University by begin typing u p p s a l a.

  3. Login with your username and password A as normal for the Joint Web Login at UU.

  4. You can easily let SUNET Mailfilter always accept mail from a certain sender (e-mail-address or domain): (The accept list may also be called a white list.)

  5. Or you can reject (brutally) from a certain sender: (The reject list may also be called a black list.)

  6. To view what mail has been marked as spam, go to the Quarantine. Please note, this is not a real quarantine which holds the mail, but rather an incident log. All mail are sent to you anyway and are put in the Borttaget or Deleted Items folder in Outlook.

    To view the incident click on the date for the message. There it is possible to tell the filter to learn that a tagged spam should not be.

  7. To change the general spam threshold for you, go to Preferences / Quarantine Settings.

  8. If you need to you may lower the Spam threshold from the UU default 6.5 to something that still is reasonable like for example 5 and save by clicking on Submit Changes. If you lower the threshold you must keep an extra eye on your Junk mail folder where the mails that are catched will be delivered.

  9. By checking the mail header X-Spam-Score: on a spam that passed the filter you can get an indication on whether or not a changed threshold level would have caught the unwanted mail.
