Book Overview

This book is not just a theoretical overview; it is a practical, hands-on guide that bridges the gap between abstract concepts and real-world implementation. Lawrence Hughes demystifies the core protocols—SMTP, POP3, IMAP, MIME, and DSN—and explains how they interact to deliver messages reliably across the Internet. With a strong focus on security, the book covers public and secret key encryption, digital signatures, and key management, making it relevant for today's cybersecurity-conscious world. The included CD-ROM enriches the learning experience with RFCs, RSA PKCS documents, and freeware tools like Eudora 3.0 and Software.com's user version.

Key Highlights

• Comprehensive coverage of all major Internet email protocols and extensions
• Real-world examples of message exchanges with program code for debugging
• Detailed explanation of email architecture and message flow
• In-depth security topics including encryption, digital signatures, and key management
• Each chapter begins with a detailed definition list for quick reference
• Comes with a CD-ROM containing RFCs, PKCS documents, and freeware clients

Inside the Book

The book is structured to build knowledge progressively. Starting with fundamental concepts, it moves into the nitty-gritty of protocol behavior. You will find annotated message traces that show exactly how emails travel from sender to recipient, including error handling and retry mechanisms. The author provides code snippets that you can use to test and debug your own systems. Security is treated as a first-class citizen, with entire sections on how to implement encrypted email and verify digital signatures. The CD-ROM is a treasure trove for learners, offering direct access to the standards that govern email today.
