Why is e-mail detected as spam?

Question / Problem

Certain e-mails are sorted out as spam by SpamAssassin. Why?

Answer / Solution

The results of the integrated SpamAssassin are written in the header of the mail, just like any other SpamAssassin. If you right-click on the mail in your Outlook and select "Message Options", a dialog appears in which you can view the Internet headers of the mail.
There you will find the spam report, which gives information about which rules have been applied to this mail:
