Anti-spam UmU

On a normal day, the university receives a few million emails, most of which are stopped immediately because the server/address that sent the email has been classified as someone who sends spam. The remaining mail is then analyzed and approx. 10,000 are then classified as spam and stored in the user’s spam quarantine. About 5,000 are classified as phishing. In the end, about 82,000 emails get through.

Of the 10,000 e-mails that are classified as spam, there may be some of these that are correct e-mails but for some reason classified as spam. A likely cause is mail with only links and from mail domains that have not received high trust scores before (e.g. have sent spam or come from a new server).

How to use the filter

If you are missing any mail or want to verify what is in the quarantine go to the following link: security.microsoft.com/quarantine

Log in with your Umu ID and password.

You will then see a list of all the emails that are in quarantine.
Mail in quarantine will sit there 30 days before they are removed.


You can mark the mail(s) that are not spam and choose to “release” them and ‘whitelist’ the sender so that they do not get stuck in the SPAM filter again, or ‘blacklist’ them and these mails will never come into your inbox. 

Initially, a mail will be sent every day if there are new messages in your quarantine.
