    The best computer book I have read

    This is a WONDERFUL book. Every computer user should buy it. The author communicates his experience and acquired knowledge with breathtaking lucidity. I have learned a great deal and now understood my system much better. I understand security issues much better and have improved my practices greatly. It is also a very valuable book about modern personal computers in general. The author offers tried and tested solutions to problems. I can verify that they work. I venture to say that this is the best computer book I have ever bought. Without being complacent, I dare to hazard the suggestion that I am considerably less likely to have my machines screwed up by enemy action than ever before thanks to reading and practising 'Degunking your Email, Spam and Viruses'.

    discusses antispam methods

    Duntemann gives a nice summary of the main antispam methods currently available in the marketplace. He points out the basic ideas behind each. Along with the advantages and disadvantages. For example, in 2003, Challenge-Response garnered wide publicity, as a spam killer. Alas, this turned out not to be so. He reveals that the manual response needed turns off some people, who sent you the initiating messages. Or, some who do try to answer the puzzle might goof. This is bad if the senders are potential or actual customers of yours. Plus, the CR methods typically check the sender address against a whitelist that you might have. Well, spammers might forge this field to pretend to be from a common and important website, like eBay or Amazon. He gives the biggest praise for Bayesians, implemented at the user's machine. He quotes high success rates when he tried it. But, as he points out, he gets a lot of mail, which makes it easier to train the Bayesian. Plus, he has the technical ability and inclination to continually retrain the Bayesian. In part, as research for this book. But the average user lacks his technical background or the will to do the retraining. A huge practical draawback to Bayesians.
