Note that this is a locked preference in 'config/prefs.php' by  
default, so it won't show up in the user's preferences. If you  
upgraded from an earlier version of Horde, chances are that this value  
has been saved to a different value than 'UTF-8'.

Your best bet for fixing this globally with the minimum amount of  
fuss, is to remove this from the users preferences. Something like

     DELETE FROM `horde_prefs` WHERE `pref_name` = 'sending_charset';

should do the trick (depending on how you save preferences).
