Not correct - since there is already a handler for multipart/encrypted  
and multipart/signed in horde.  see below.

Most likely your problem, then, are these lines in  
*horde*/config/mime_drivers.php:

$mime_drivers['horde']['security']['inline'] = true;  
$mime_drivers['horde']['security']['handles'] = array(      
'multipart/encrypted', 'multipart/signed');  
$mime_drivers['horde']['security']['icons'] = array(
     'default' => 'encryption.png');

Obviously, if you turned inline global settings of multipart/encrypted  
or multipart/signed off then of course no PGP/MIME messages will be  
displayed inline since the application/pgp-encrypted types etc. *must*  
live in a multipart part - if the parent multipart is set not to be  
inlined, then obviously the children won't be shown.
