This will be an intense, fast-paced, full-day tutorial intended for people who have already been exposed to sendmail. It is not intended as an introduction to sendmail. After introducing a bit of the philosophy and history underlying sendmail, this tutorial covers: * The basic concepts of configuration: mailers, options, macros, classes, keyed files (databases), and rewriting rules and rulesets. * Day-to-day management issues, including alias and forward files, "special" recipients (files, programs, and include files), mailing lists, command line flags, tuning, and security. * Configuring sendmail using the M4 macro package. This tutorial describes the latest release of sendmail, version 8.10. Intended Audience Systems administrators who want to learn more about the sendmail program, particularly details of configuration and operational issues. This tutorial will not cover mail front ends.

Eric Allman was the original author of sendmail. He is currently the Founder and Chief Technology officer if Sendmail, Inc. He was the Chief Programmer on the INGRES database management project and an early contributer to the Unix effort at Berkeley, authoring syslog, tset, the -me troff macros, and trek. He received his M.S. in Computer Science from U. C. Berkeley in 1980. He designed database user and application interfaces at Britton Lee (later Sharebase), and contributed to the Ring Array Processor project for neural-network-based speech recognition at the International Computer Science Institute. He was also Chief Technical Officer at InReference, Inc. He co-authored the ``C Advisor'' column for Unix Review magazine for several years and was a member of the Board of Directors of USENIX Association. Eric has been accused of working incessantly, enjoys writing with fountain pens, and collects wines which he stashes in the cellar of the house that he shares with Kirk McKusick, his partner of 20-and-some-odd years.
