Explanation SPAM statistics
Since the beginning of June 2007, the IT Center has been using two identical Ironport appliances as spam filters, virus filters and spam detection for the entire university. Through these systems, more than 82 percent of the spam emails have either not arrived at all or have been marked as such. Currently, more than 77,5 percent of delivery attempts can be rejected directly with these new systems because the emails were sent from mail servers with a bad "reputation". Another 1,2 percent of emails are not accepted due to invalid senders or recipients. This significantly reduces the load on the university's mail servers and the mailboxes of the users. The remaining emails which are accepted by the systems and distributed to the users are freed from virulent attachments if necessary and - if they are spam - marked as such by the addition *****SPAM***** in the subject.
