Just a quick one. The format of ip_blacklist, is it: xxx.xxx.xxx.xxx - individual IP's or xxx.xxx.xxx.* - for a full class C xxx.xxx.*.* - for a class B or xxx.xxx.xxx.0/24 - for a class C xxx.xxx.0.0/16 - for a class B or do I have to add each IP? There are some ranges I would love to kill off completely for email reception (Korea, China to name but a few....) but leave them for other purposes. Up to now I've used iptables, but that kills all stone dead as it should. Anyhow, info on the above would be useful. Cheers, Pete
