The science behind the service that sifts through your spam. Junk mail is detected by scanning the message for common warning signs. Was the message sent from a blacklisted network? Have the headers been tampered with to hide the sender? Does the subject line use all capital letters?

If you manually mark an email as spam, it also refines the scoring system for future emails.
