telnet localhost 2000 hen trying to use avelsieve

Hi,

I'm trying to get sieve to work.
I keep getting the error connection refuised when i try
telnet localhost 2000

I used the guide found in the discussion.
So i also get the error when i try to use it in webmail.

(Also can't find the log that is produces by avalsieve)
Trying it on a clean installed MacOS X Server 10.4.9 system.
