[horde] Horde problem with large mailboxes

[Kevin Konowalec]

You know the little icons in the inbox that indicate whether or not a  
message has an attachment?  Well in order to do that, as I understand  
it, each message has to be opened and examined to determine whether or  
not it has an attachment.  We found that it was a SEVERE performance  
hit to have that turned on.
