Throttling is not the solution to fight spam originating within your network. If you know who is doing it, boot him. If you don't, identify who it is, then boot him. Period. Why are you playing paddy cakes with a spammer on your network? If this spam is due to php/sql injection, fix/patch or eliminate the hole that is being exploited instead of trying to throttle it. -- Stan
