Spam is a scourge for anyone who uses e-mail. What can be done to stop spam?

When it comes to spam, there is a constant battle between those who send out spam and those who try to stop it from reaching our mailboxes.

A technique used in this context is so-called graylisting. If you want to know a little more about how graylisting works, you can look at this page.
