Sorry about that, I meant to mention that also and got side tracked.
You will need to set up a custom template based on the following built-in template:
/etc/e-smith/templates/home/httpd/html/horde/config/mime_drivers.php/160html
Then create another custom template which does not have a base template:
mkdir -p /etc/e-smith/templates-custom/home/httpd/html/horde/imp/config/mime_drivers.php/
create a custom template file in here with the following data:
/**
* HTML driver settings
*/
$mime_drivers['imp']['html']['inline'] = false;
$mime_drivers['imp']['html']['handles'] = array(
'text/html');
$mime_drivers['imp']['html']['icons'] = array(
'default' => 'html.png');
/* If you don't want to display the link to open the HTML content in a
* separate window, set the following to false. */
$mime_drivers['imp']['html']['external'] = true;
You want to set html inline to true in each of these files.
That should get you there. If you don't want to test with templates edit /home/httpd/html/horde/ directly, but realize you will loose those changes next time the server is updated/configured. Templates are great!
Here is a Horde reference for inline html:
