[Dovecot] Problems getting Squirrelmail and Avelsieve to connect to Pigeonhole

[Steve]

Hi,

I have been going around in circles trying to find the solution. Many 
others appear to have the same problem, but never a solution or explanation.

I am running Dovecot 2.0.21 under Fedora 16.

All components are running on the same server, whose IP address is shown 
as '192.168.x.y'.

The dovecot -n output is:

On attempting to connect to the managesieve port from Squirrelmail, 
using the 'Filter' button i get the following error message:

    /*Could not log on to timsieved daemon on your IMAP server localhost.*/
    /*Please contact your administrator*/


Running/*# /usr/sbin/ngrep -d lo port 4190 */produces the following trace:

I hope that someone can provide a way to get the filter management 
working as I am more that happy with the way Dovecot and Squirrelmail 
are working, but just want to add server-side filtering, especially 
tagged mail produced by Spamassassin :)

Many thanks

Steve
