Hi all
I am using dovecot at home for privat use and i found a lot of documentation here on the web. But you know, i am an old fashion guy and i like books. Is there a book on the market that will help me with understanding dovecot more and the configuration options ?
This book apparently covers some of Dovecot: http://www.amazon.com/Pro-Open-Source-Mail-Enterprise/dp/159059598X
It's geared toward building a complete mail server solution, so it's not dedicated to Dovecot. How much of Dovecot it covers I don't know, as I've not read it.
It was apparently published in Sept 2006, 3.5 years ago. Standard caution applies: some/much of the technical information may now be incorrect as things have changed in the software over the 4+ year period since the author put pen to paper, so to speak.
This is the most recent book I could find that covers a little bit of Dovecot. There doesn't appear to be a "Book of Dovecot". Dovecot is covered a bit in The Book of Postfix, but it was published in 2005, so it will be even farther out of date.
The book linked above may be worth the read for general architectural setup.
