Please edit /usr/local/etc/fml/main.cf if needed, though already configure rewrites main.cf to fit your environment.
main.cf is the most fundamental configuration to control fml8 basic features: fml version control, library path, virtual domain et.al.
Instead, the detail of each ML configuration depends on config.cf of each ML such as /var/spool/ml/elena/config.cf for elena ML. "config.cf" can control customization of header, filter rules, member file locations et.al.
