write this book and someone else would have Indeed it would have been better "want to write this book and hoped someone else would have Indeed it would have been better someone else hadThe book contains an exceptional amount of background information on mail protocols and procedures and a lot of detail on Exim itself If I had 5 weeks to read and absorb it all it would be wondersfulFor busy systems administrators using this book is a hard work finding the information needed is slow and then understanding it is difficult Dr Hazel s writing style is terse and rather like a mathematical text There is no fluff in it s 600 pages I find myself reading sentences repeatedly trying to understand them Also the implications of certain information is not made obviousHis lack of realistic examples is also a serious short coming He losses over remote access of mail via POP IMAP and SMTP authentication even though this is the most common way of accessing mail these days I would especially like to see discussion of an ISP type mail server with multiple domains which is lackingFinally there is lack of reference material in the appendices a short form listing of command options and configuration. Exim delivers electronic mail both local and remote It has all the virtues of a ood postman its easy to talk to reliable efficient and eager to accommodate even the most complex special reuests Its the default mail transport agent installed on some Linux systems runs on many versions of Unix and is suitable for any TCPIP network with any combination of hosts and end user mail softwareExim is rowing in popularity because it is open source scalable and rich. Ourself This won t replace the official documentation especially since it coversTo Write This Book And
An Old Outdated Versionold outdated version EXIM but covers enough to be worthwhile as a supplement Still I was rather disappointed that much of what I was trying to do such as set up spam filtering wasn t covered by the book and that I had to Dead-End Road Mysteries go online and read through back mailing list archives and read official documentation toet the job done From any other publisher I wouldn t feel too bad about that but from O Reilly I ex This book was a disappointment While first reading the book I thought it was "great however after i tried actually configuring the "However after I tried actually configuring the program I realized this book included only superficial examples Any serious configuration reuired an in depth understanding of the exim program far beyond the overview of this book The necessary bits of information are scattered throughout the book Unfortunately these bit were often not referenced in the Index This reuired my reading large sections trying locate a specific bit of information The book s index is weak It often includes references to variables options and features that reuires the specific name of the information being sought to locate In contrast Exim s downloadable pdf documentation has the advantage of being uickly computer searchable After being frustrated with this book I turned to the downloadable documentation and found it much useful. Is easy to configure You never have to deal with ruleset 3 or worry that a misplaced asterisk will cause an inadvertent mail bombWhile a basic configuration is easy to read and can be created uickly Exims syntax and behavior do et subtle as you enter complicated areas like virtual hosting filtering and automatic replies This book is a comprehensive survey that provides uick information for people in a hurry as well as thorough coverage of advanced material. ,

AdditionWarning This Book Is Forthis book is for 3 and version 4 is now available although version 3 is still used If you can t or won t run then IMO your only two real alternatives are postfix and Exim I still believe that is a better choice but both postfix and Exim are still uite Valors Measure goodIf you decide to run Exim there are few people who couldive you a better insight into how the program is configured and how it works internally "Than The Author Of "the author of program Phil HazelHowever keep in mind that the book is primarily oriented around version 3 of this program and version 4 with some significant changes has already been produced More information is available at URL Exim the MTA would be an appropriate book for someone who does not know anything about e mail and suddenly needs to manage a server and EXIM would be a BFI Film Classics good e mail server for this person to use EXIM is the default MTA in Debian and other Unix distributions tooExim the MTA has been written entirely except for contributed patches by Philip Hazel who continues to maintain it In conclusion if I wasn t already in the habit of setting up mail on new machines that appear within my aegis a habit that once Iot the hang of it has reduced the care and feeding of my e mail servers to an absolute minimum I might select exim as an MTA to specialize in To restate it s too late for me but save In features such as the followingCompatibility with the calling interfaces and options of Sendmail for which Exim is usually a drop in replacementLookups in LDAP servers MySL and PostgreSL databases and NIS or NIS servicesSupport for many kinds of address parsing including regular expressions that are compatible with Perl 5Sophisticated error handlingInnumerable tuning parameters for improving performance and handling enormous volumes of mailBest of all Exim.
