Connection timed out

[Jérôme Tournier]

Hi,
i have the following problem:
i installed imp + qmail + courrier-imap. 
When i select the INBOX.trash folder, i can go in it, but i can't come back 
to the INBOX folder : i am disconnected. The apache logs tell me:
<br>
<b>Warning</b>:  Connection failed to suzanne,143: Connection timed out 
(errflg=2) in <b>/var/www/html/horde/lib/horde.lib</b> on line <b>0</b><br>


Another problem is that i can't create any folder. I am also disconnected 
whith the same log.

Here is my config:
courier-imap-1.3.10.tar.gz
horde-1.2.6-1rh7.noarch.rpm
horde-pgsql-1.2.6-1rh7.noarch.rpm
imp-2.2.6-1rh7.noarch.rpm
php-imap-4.0.4pl1-9.i386.rpm


Any idea ?
Thanks
