Negative Positive
Title: A disappointment
Review: 5 chapters and 124pages of introduction to DNS, SMTP, and assorted blah. The author does an ok job of walking through the Postfix internals - 30+ pages just on postfix lookup tables. The book really disappointed in describing Postfix server operations. In fact, there appear to be a few errors. Following the book verbatim led to a BROKEN postfix server. Fortunately, Google knows all.
Is the review positive or negative?
