filter rules server-ased?

[Markus Heller]

Dear community,

I have a question, as I was away the last week, and I have installed 
squirrelmail to access my emails from outside. 

Since I have registeres on a number of mailing lists, I get about 300 mails 
per day, most of which will be filtered away into certain folders. 

When I was away, I logged into squirrelmail and I saw more than 1800 email in 
my inbox! Not having had my kontact / kmail client I assume that the 
filtering is all done on the client side.

Is there a way to do the filtering on the server side? (I have the feeling 
that Sieve is what I'm looking for, but I don't know anything about it)

Regards
Markus
