For those of you who have fallen in love with Zimbra, or just want to know more, you may want to check out this book from Packt Publishing.
They sent me a copy to review a month ago and it’s jam-packed with all kinds of nerdy goodness. For someone that just wants to find out more about Zimbra, it’s good, but for those of you that want to put it through it’s passes, you’ll love this book.
I think it runs around $40 normally, but you can get it on Amazon for around $30.
