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: <quote>

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: <quote>

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
