By default HTML viewing message for Horde is disabled

To enable edit the following file

/usr/local/cpanel/base/horde/imp/config/mime_drivers.php

And change the following line

from

$mime_drivers['imp']['plain']['inline'] = false;

to

$mime_drivers['imp']['plain']['inline'] = true;

Syntaxis has been little bit changed, so now you need to update the following section in /usr/local/cpanel/base/horde/imp/config/mime_drivers.php file:

/* HTML driver settings */
'html' => array(
/* NOTE: Inline HTML display is turned OFF by default. */
'inline' => false,
'handles' => array(
'text/html'
),

to

/* HTML driver settings */
'html' => array(
/* NOTE: Inline HTML display is turned OFF by default. */
'inline' => true,
'handles' => array(
'text/html'
),

Restart cpanel, exim and relogin you email account

By default this is set to “false”, so your change will be overwritten after next cPanel update, so consider to append the following to get this enabled after every upcp

vi /usr/local/cpanel/scripts/postupcp

and append:

replace "'inline' => false," "'inline' => true," -- /usr/local/cpanel/base/horde/imp/config/mime_drivers.php

Enjoy!
