I recall suggesting, only slightly tongue-in-cheek, that if the US
PATRIOT Act, instead of permitting the FBI to read everyone's emails,
had *required* it, the spam problem would have been solved fairly
quickly....

I would use any review article written in the
last decade to justify that spam reduction can be achieved to a 99%
rate with computer programs. For example, see: Thiago S. Guzella, Walmir
M.
Caminhas, A review of machine learning approaches to Spam filtering,
Expert Systems with Applications, Volume 36, Issue 7, September 2009,
Pages 10206-10222, ISSN 0957-4174, 10.1016/j.eswa.2009.02.037.
(http://www.sciencedirect.com/science/article/pii/S095741740900181X)
Receiving 5 or 6 e-mails per user per day is not much, but it should
be compared with the actual amount of spam you are receiving at the
server in order to evaluate the performance of your spam filtering
policy. A 100% performance could be achieved, as several people said
above, unplugging the cord, or turning the mail server off. Another
option that has not been considered would be hiring a person, or team,
depending on the volume of e-mail you receive, to read every single
e-mail received and manually classify it. I wonder if your bosses
would want to deal with the extra monetary costs and the privacy
violation issues that this solution would bring along. Best regards,
