A very easy to read book that goes through various aspects of spam, and how to minimise your exposure to it. Of course, you need to be familiar with email, because you're getting spam, aren't you? But other than that, the technical background needed to understand the authors' points is minimal.
They explain clearly and in simple terms why spam exists, and the common ways in which spammers can get your email address and the typical characteristics of the spam that they send.
Various simple antispam techniques are shown. These are mostly aimed at the end user. For example, they suggest that you do not post your email address widely on the net. Or, if you post it on your web page, you choose something like drawing it in an image, so that a spam bot cannot harvest it. Or having an obscure address, like j0e3892@someisp.com, instead of a simple joe@someisp.com. So that your address cannot be found by a dictionary attack.
The problem with the authors' suggestions is that they undermine a lot of the usefulness of email. For example, having a short and simple address helps others remember it and type it correctly. And being able to just disseminate addresses widely was and still remains a core utility of email.
