Yes, I completely agree with that. However unfortunately I cannot do this 
without major restructuring of the Horde code. You must remember that I am 
working in a web-based environment - I am not afforded the same luxuries as 
the native client guys.

Yes there is a need to re-read the message, as I have no way to save messages 
across page loads.

Well, unless I save them in the session variables, which means the server will 
inevitably run out of memory as I would have to store all messages that I 
read, for every mailbox that every user of the webclient accesses, while 
keeping them resident for a reasonable time period (as I have no idea when 
the next page load will be).

:-/

All I know when I obtain a "read object" request is the UID of the object that 
needs to be loaded.
