3.4 Compile-Time Macro Reference

In this section we present each compile-time macro (or group of them) in alphabetical order. There are so many to choose from that you will probably be better off first scanning Table 3-2 for any that seem interesting, then going to that particular section for a more detailed look.

As you learn more about sendmail you might find that a particular option or feature might require that one or more of these compile-time macros be turned on or off. You are encouraged to return to this reference section to study each such compile-time macro before redefining it and rebuilding sendmail.
