How about a server side email filter?

[mutter]

How about implementing a user configurable email filter on the server side? I can filter my email effectively using outlook express, but that doesn't help when using webmail.

If there isn't some generic server side filter "plug-in" available, how about adding this plug-in? It would at least benefit those using squirrelmail for webmail:

I thought Horde was the more famous one.
