This is a great book if you are seasoned Sendmail admin with good C programming skills. I give 3 starts because it is so hard to understand.

I've been using sendmail for 3 years and I just tried Qmail and Postfix. I have chosen Postfix because it's so darn efficiant and configurable.

Viktor Duchovni, is a great help on the online community and the online docs are just as detaild as this sendmail book.

If you are stuck on sendmail then get this book.

But try Qmail and Postfix if you can...

BTW... RedHat lets you choose between Postfix or Sendmail. That means a lot to me.

If you are a mail admin and don't use this book, you are either doing it wrong or are a genius.

Anyone who is serious about sendmail administration and configuration must use this book.

sendmail is far to complex to be used w/o a great reference such as this.

Without a doubt, this is the best reference book there is on Sendmail. No other books come close.
