Internet Email Protocols: A Developer's Guide
seeks to fill the gap in published material on the nitty-gritty details of how Internet e-mail really works. With patient precision, the book succeeds in delivering a definitive examination of the various e-mail standards defined by a slew of public Request for Comment (RFC) specifications.
The text is designed for software developers who need to know everything about Internet e-mail--from protocol communications down to the definitions of individual ASCII characters. The book begins with an overview of the standards process and a thorough history of e-mail. It then presents the key protocols and specifications that collectively form what we refer to as "Internet e-mail." It carefully defines all the elements of mail messages themselves, and then presents the Simple Mail Transport Protocol (SMTP)--the lifeblood of mail movement on the Net.
Subsequent chapters lay out POP, IMAP, MIME, PGP, and other crucial standards in consistent detail. Along the way, the book continually references the RFCs. An accompanying CD-ROM contains all of the relevant RFC documents and the source code for publicly available e-mail applications. When it comes to the inner workings of e-mail, you won't find a more complete, and readable, presentation. --Stephen W. Plain
Topics covered: Internet e-mail overview, mail message fields, SMTP, MIME, POP, IMAP, filtering, mailing list processing, security (services, frameworks, extensions, MIME security).
From the Back Cover
Internet Email Protocols gathers, in one comprehensive and convenient resource, the key technologies that form the underlying mechanics of Internet email. It provides developers and networking professionals with in-depth explanations of essential concepts and a framework for understanding how and why these technologies fit together to provide cohesive email services. This book shows how to troubleshoot and solve email problems, how to evaluate different implementations of the standards and protocols, and how to be better equipped when faced with the challenge of writing programs that process email.
For each chapter, the author presents an overview of the material, detailed information, and any important extensions and advanced uses of the protocols being discussed. You will find in-depth descriptions of:
* Message formats, covering the structure of message headers, the various fields, and the intricacies of email addresses, as well as a detailed treatment of MIME
* Mail transport technology, focusing on the SMTP protocol
* The most current versions of the POP and IMAP protocols
* The mechanics of filtering email, with an emphasis on applying this knowledge to blocking unsolicited bulk email
* The mechanics of mailing list processing, with an emphasis on applying information from earlier chapters
* Security details, covering authentication, digital signatures, encryption, and anonymity
In addition, the appendices provide example folder formats, a discussion on UNIX folder locking, and an overview of the languages commonly used for email development. The accompanying CD-ROM contains all the RFCs referenced in the book, as well as the source code for several popular email packages, including Sendmail and Procmail. Bringing together information that is scattered among many RFCs, software packages, and lore, this one detailed book is an important resource for anyone developing email applications. 0201432889B04062001
