As e-mail traffic continues to increase, system administrators must be able to guarantee that their e-mail servers can deliver reliable performance today and bear larger loads tomorrow. sendmail Performance Tuning is a handbook for building, tuning, and testing e-mail servers using sendmail to function more efficiently, handle more messages, and resist both accidental and malicious load-related incidents. This practical guide begins with an introduction to sendmail and performance tuning. Author Nick Christenson describes best practices for building, installing, and maintaining a system and then details proven techniques for tuning e-mail relaying, reception, and sending. His strategic guide to configuration and security is followed by precise directions for managing bottlenecks and load testing. By the book's end, readers know exactly how to optimize system performance.
Nick Christenson designed and implemented Internet systems, including email, for EarthLink Network, Inc., during its period of rapid growth. He also worked for Sendmail, Inc., as a senior software engineer and senior technical consultant. Nick is currently a senior analyst for Sistina Software. He has given talks at the USENIX Symposium on Internet Technologies and Systems and at the O'Reilly Open Source Conference. He has written articles for ;login:, the Erlang/OTP User Conference, and USENIX LISA. 0321115708AB08232002
