User-Configurable Macros and Classes

User-Configurable Macros and Classes

The sendmail.cf file defines your mail network by assigning each element in the network a macro or class value. The default values in your distribution sendmail.cf file will not work without some modification.

Instead of modifying your sendmail.cf file directly, you can use the /usr/etc/configmail script. It takes your input, saves it in sendmail.params, and configures the appropriate macros and classes according to your sendmail environment.
