not a simple book
More so than browsing. Email is probably still the most important application on the Internet. But setting up an email server can be fraught with complexity under unix or linux. In response, Taylor offers a straightforward guide to installing and running a server for a small company. One attraction about the book's software is that it is all open source and free.

Understanding enough of it to usefully maintain it is another matter. But Taylor gives enough explanations of various key applications. Like Postfix and Procmail and SpamAssassin. This is still not a simple book. For example, SpamAssassin's classification of an email as possible spam is a statistical assessment based on a set of rules typically seen in spam. But it is quite possible for an email that you want to get hit by this and marked as spam. You might want to experiment with SpamAssassin's settings until you are comfortable with the results.
