I can read, delete, move, do drag and drop emails just fine.

When I send a new (or reply) message, the compose window freezes for  
about 30 seconds and then I get a white screen.
The email is sent, and saved into the 'Sent' folder (though Horde logs  
says otherwise).

I've attached the imap debug ouput.

This is what I get in Apache's log file :
[error] [client 192.168.1.166] PHP Warning:   
IMP_Compose::buildAndSendMessage(): failed to call filter function in  
/var/www/html/horde/imp/lib/Compose.php on line 694, referer:

This is what I get in /tmp/horde.log :

 From what I could track down, it seems to be hanging for about 30  
seconds here  :
Horde/Imap/Client/Socket.php: function _getLine(), line 3751
         $read = explode(' ', $this->_readData(), 3);
