KPU Spam Filtering Statistics

 

All email received at KPU passes through multiple filters to prevent spam email and viruses from reaching the university's email system. Although this system is robust and constantly updated, a small amount of spam gets through because it is not detected as spam. 

The graph below depicts the monthly statistics from the email filtering system.  The blue portion of the column represents emails that are delivered.  The red portion is the emails that are identified as spam or viruses and therefore rejected. The numbers are correct; we are talking about millions of emails.
