About the White Paper:
Blocking unsolicited commercial e-mail or "spam" is an increasingly important
but difficult task for IT staff. Great effort has been spent developing
sophisticated content filters that can identify and score messages to determine
their level of "spaminess." While these systems continue to improve with the
introduction of techniques such as bayesian filtering, their efficacy will always be compromised by spammers, with a money motive, who will continually
modify their content to get through these filters. Some senders of unsolicited
commercial e-mail have taken the process of avoiding content filters one step
further -— using widely available tools to scan their messages through popular
antispam packages before they are sent so they can modify their content to
make sure it gets through. |
