MTA Performance Comparison: sendmail & postfix on *BSD
Brad Knowles
Topic: Email/DNS/Spam
Audience: Intermediate users
Description:
Two popular SMTP Message Transfer Agents (MTAs) will be tested on three different implementations of BSD Unix. Standard performance tuning enhancements will be made and benchmarked for comparison on all three platforms. Details regarding hardware, OS, software, and testing configurations will be provided, including selections of configuration files, selections from sample test runs, etc....
The MTAs to be tested are sendmail and postfix. The OS platforms to be tested are FreeBSD, NetBSD, and MacOS X). The testing tools include SPECmail2001, Postal, mstone, and smtpsink/smtpstone (from postfix).
Complete charts and graphs will be generated, and conclusions regarding the relative performance of each MTA relative to each OS will be presented. Directions for future testing will also be presented. Note that no testing of anti-spam or anti-virus features will be attempted.
Also note that different machines will be used for each OS, and therefore test results across OSes are not likely to be comparable.
Finally, note that OpenBSD is not being tested, partly for reasons of expediency and partly because the author believes that it is not likely to perform radically different than NetBSD in this application.
Prerequisites:
Intermediate knowledge of how Internet e-mail works, intermediate knowledge of how Unix and Unix-like OSes work.
