I agree that client specific folder configurations fit even less into  
the current concept of IMAP folder annotations.

But my argument is not about the length restriction or the actual  
server implementation. There is a concept behind the RFC describing  
IMAP METADATA. And it is about storing simple name value pairs. NOT  
about having a general database for each folder.

And to me this is the issue we are discussing here: storing complex  
data for a folder. It may be a "simple" array or it may be a set of  
values for each client.

Annotations as described in the IMAP METADATA extension are useful and  
they have served Kolab well in the past years. And I don't see us  
stopping to use them. I just want to limit their use to the simple  
task they were meant to fulfill.

So I would like to extend our format definition so that we avoid  
misusing the annotations. Please let us define a special folder object  
that holds any data that lies beyond the simple name/value concept of  
annotations.

Cheers,

Gunnar
