Negative Positive
Title: Padded, imprecise, superficial
Review: The books is definitely padded; all these Unix books seem start off with a hundred pages about the most mundane admin tasks that every admin knows how to do ANYWAY -- "Postfix" is no exception in that regard.I took some time to check the pages between the padding, and found several errors, omissions or imprecise statements about how Postfix works.All in all the book is quite superficial when it comes to how to actually USE the stuff described -- examples are missing like:"If I get spammed like this, what can I do to prevent this?"This somewhat limits the use of the book, since you have to find out that stuff yourself, by trial and error.It's hard to say if the book is targeted at an admin (then he/she should know SMTP and DNS -- and be annoyed by the padding) or a newbie (thenhe/she gets some info, but might end up with a system that's uglier than it needs to be).
Is the review positive or negative?
