better by the day and this book is one must-have reference material, one of the

only two I have; from O'Reilly. The other is the book on DNS and BIND.

O'Reilly books are neat but they are not available for a *FREE* download, atleast they have to carry an HTML-ized tarball of the book to do justice on

the topic/subject; all the more important if the same is under the GNU/GPL.

The author, Philip Hazel, is a great help in the Mailing List too ! When the

list is mentioned, I just cannot hold back thanks to Yann Golanski for his

Exim papers and Suresh Ramasubramaniam for his enthusiasm in helping listers.

This book is a *smart* buy for Mail Administrators' and for students' wanting to

learn a *free* MTA which is as good, if not better; than Sendmail.
