Blocking Incoming Spam

  • Until computers are sapient, they won't be able to tell with 100% reliability whether or not a message is spam (AKA unsolicited commercial e-mail or UCE)
  • Unexpected mail can be a terrible nuisance... or a delightful surprise!
  • The best we can do today is watch for telltale signs of spam
  • Fortunately, most spam bears one or more of these signs and is easy to recognize mechanically
