Appendix E. A sendmail Reference

This appendix provides details of the syntax of the sendmail command, of the sendmail.cf file, and of the m4 macros that can be used to build that file. It describes where to obtain the latest source code for sendmail and how to compile it. This appendix is a reference, not a tutorial. Refer to Chapter 10 for a tutorial on sendmail configuration.

We start the appendix with information on locating, downloading, and compiling the latest version of sendmail.
