Appendix A. The mc Configuration Macros and Directives

The m4 method of creating a configuration file is introduced in Chapter 4, but that chapter details only about one-third of the mc configuration macros and directives that are available. The others are documented in chapters that deal directly with a particular aspect of the configuration file. To facilitate the process of locating these items, and to provide you with a way to see how they interrelate, this Appendix lists the mc configuration macros and directives in alphabetical order.

Note that most of these mc macros are defined with the define method. For example:

define(`ALIAS_FILE', `/etc/mail/aliases')

These we show without trailing parentheses in the table. Others are self-defining. For example:

CANONIFY_DOMAIN_FILE(`/etc/mail/canonify-domains')

These we show with trailing parentheses in the table. For example:

ALIAS_FILE             ← use define( )
CANONIFY_DOMAIN_FILE( )← use by itself
