Believe me, if there was a newer book, I would have gladly bought it. It did worry me that it was as old as it was, but I gather that the email protocol has changed very little over the past 15 years.
A HOWTO that has been around for a few months is still nice, especially if the author maintains it so that the flaws and errors are corrected as people point them out. I am really surprised at how no one really adopts the crowd-source wiki approach. It seems that everybody wants their document in a sterile bubble of web space where people can look, but can't touch.
