The "Bat Book" belongs at your desk.
|von Bryan Costales|
I knew nothing of sendmail (or Unix!) when I was asked to implement a new mailhub, mail-gateway, and mail-relay. While I was learning ls, cp, and vi, I was also learning how to compile, install, and configure sendmail! -Thanks to this book.
If you're going to be involved with sendmail, you've heard of the sendmail.cf file. Don't be scared, just jump in and learn it once and for all. With this book, you'll quickly master the .cf file and amaze your friends by configuring SMTP mail servers in no time. More than the complete sendmail reference, this book gives many real-world examples you can adapt to your environment.
The only drawback concerns the release of sendmail 8.9. With the significant changes between 8.8 and 8.9, O'Reilly would do us all a great favor by releasing a 3rd edition covering what's new in 8.9. Regardless, the "Bat Book" will maintain its position within arms reach of my keyboard.
THE sendmail book
Sendmail has it's reputation already. One may also consider qmail and postfix. This book presents nearly every detail of sendmail on over 1000 pages. One of the authors is even the creator of sendmail. The book helped me to understand the sendmail configuration file, especially the complicated regular expression substitution patterns, which are very arcane but powerful. For UNIX admins it's a must have, because there is no other way to get the infos to handle sendmail mail servers. But it takes quite some time to get aquainted with sendmail and this book does not make it any faster. It's a complex topic and not really fun, but effective.
viel zu sendmail, jedoch etwas unübersichtlich
Dieses Buch eignet sich gut als Nachschlagewerk, ist jedoch nicht besonders gut strukturiert. Beispielsweise hätte ich mir eine sorfältigere Gegenüberstellung der m4-Konfiguration mit den entsprechenden Einträgen in der /etc/sendmail.cf gewünscht.
