Hi,
you can try to do this:
Open /etc/horde/imp/mime_drivers.php
Search for:
/* HTML driver settings */ 'html' => array( /* NOTE: Inline HTML display is turned OFF by default. */ 'inline' => false,
Replace “false” with “true”.
Best of all restart “apache” or reboot the server.
i hope, it helps.
Regards
O. Bertgen
