What's available are the somewhat dated (but still very useful) books, http://www.postfix.org/documentation.html, and the list archives. After reading either of the books, you can brush up on the newer features in one of the postfix.org tutorials. The most important things to peruse are: * http://www.postfix.org/ADDRESS_REWRITING_README.html * http://www.postfix.org/ADDRESS_CLASS_README.html * http://www.postfix.org/OVERVIEW.html * http://www.postfix.org/master.5.html The top portion of http://www.postfix.org/postconf.5.html covers general main.cf syntax. After that, SASL_README, TLS_README, SOHO_README, ... cover more focused topics. Be especially weary of third-party HOWTOs that recommend fashionably "strong" TLS settings. These are most likely to be counterproductive. -- Viktor.
