Appendix A.1	FML Filtering


Fml has filtering mechanism based on mail header and body after fml
2.2 (2.2 officially but fml 2.1 current unofficially). You can
deny/reject mail with some patterns. If you can find
$USE_DISTRIBUTE_FILTER in fml source, the version has filtering
function.


In default fml filtering is off. Firstly you should turn on it.
