overview and working methods
Anti spam tools are programs that help you deal with
the mass volumes of Unsolicited Commercial E-mail (UCE or Spam)
that many of us get today. They help you by deleting
mail off the server that triggers certain criteria, by e-mailing
the postmaster at the domain the spam originates from, and more.
The next few pages should show, what spam exactly is, which tools are currently available, and how spam can be rejected even on the mail server.
