Like other list changes, you can use ezmlm-make with the ‘-e’ or ‘-+’(*) edit switches together with other desired switches and arguments. An existing list can be made message moderated with:
% ezmlm-make -+m DIR
or by creating the DIR/modpost file(*7).
To add remote administration, add the ‘-r’ switch or create the DIR/remote control file. To add subscription moderation, add the ‘-s’ switch or create the DIR/modsub control file.
