21.7 Macros with mc Configuration

The various FEATURE( )s of the mc configuration technique primarily use uppercase, single-character macro names. The complete list of them is shown in Table 21-5. Some of these are defined by using the appropriate mc configuration command (as you'll see later). Others are predefined for you by the mc configuration technique. See the appropriate section reference for a full description of how to use each macro.

The version of this mc configuration

A few macros can be defined by using an mc configuration command. For example, here is how you define the BITNET relay with the BITNET_RELAY keyword:

define(`BITNET_RELAY', `host.domain')

See Table 21-6 for a list of the mc macros that can be defined. The leftmost column in that table shows the keyword to use.
