I am trying to come up with a good server based email filter. The thing 
is that it should be web based. The only thing I have seen is 
http://www.uvm.edu/opensource/?Page=procbuilder.html anyone know about 
this, or another one? Should I go with a web based email client which I 
am wanting to add at some point anyway? That is assuming they have 
filters built in, and don't apply just for themselvs.

Thanks
Patrick
