A Useful Table

The m4 method of creating a configuration file using an mc configuration file is covered in Chapter 4[3ed]. In Table 4-1, we list nearly all of the macros available to use when creating your configuration file.

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

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

In the table, these are shown without trailing parentheses.

Others macros are self-defining. For example:

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

In Table 4-1, these are shown with trailing parentheses. For example:

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