Postfix main.cf

In this main_cf_files.cfg example, we specify a SuSE Linux version of the Postfix main configuration file, /etc/postfix/main.cf.  Note the use of the =pikthostname macro, which is a PIKT built-in that resolves to the current slave system hostname.

On the piktmaster system, we would install the main.cf file to the venice SuSE Linux system with the command:

# piktc -iv +F main.cf +H venice
