Despite the title, there's little useful programming advice in this book. If I was being particularly mean, I'd say it was a rehash of some RFCs and the JavaMail API spec.
It gives a decent overview of POP3, SMTP, IMAP and ACAP. The IMAP treatment is quite good, but this is nothing you couldn't get if you read the relevant RFCs a couple of times.
The code examples are OK, but of limited generality.
If you can spare the cash, buy it, but if you're looking for the one true path into mail programming, this isn't it.

Reading this book I found out how easy it was to write your own mail clients to send and recieve email. It covers all the IP protocols (SMTP, POP3, IMAP etc.) you need to know about and gives plenty of references to other sources (e.g. relevant RFC's).
The only downside is that Micorsofts implementations of many of these protocols is weak so this book explains stuff I want to do but MS won't let me.

As a guide to Internet mail protocols, this is a pretty decent book. The "programming" aspect is somewhat disappointing. There is too much of a UNIX emphasis, too much emphasis on using Perl (not many professional developers use Perl and anyway it's only really useful on a UNIX platform) and not enough material on the JavaMail API. In fact, the coverage of the JavaMail API is especially disappointing, amounting to little more than a list of classes and their methods (no explanation of what they do) with a handful of brief code samples.
