[Dovecot] ManageSIEVE services with Dovecot cvs-LDA?

[OpenMacNews]

hi all,

has anyone had any success in getting the current dovecot cvs-lda's 
implementation of CyrusSIEVE responding to a ManageSIEVE client?

in particular, i'm hoping that one can use, e.g., Mulberry's Client- & 
Server-side sieve editor:

    <http://www.cyrusoft.com/sieve/sievescreens.html>

if i telnet to my dovecot box's sieve port ( = 2000) i get no response at all 
...

telnet localhost 2000
    Trying 127.0.0.1...
    telnet: connect to address 127.0.0.1: Connection refused
    telnet: Unable to connect to remote host

net-stat shows nothing on port 2000, and, afaik, there's no mention of a server 
on the wiki ...

so i'm either doing something wrong, or "it" is simply not there.

has a sieve server been implemented?  any plans?

thx!

richard
