this might work. We had an AD connector for the kolabd daemon but I  
don't know if that one still works fine. I added Thomas on cc he might  
know more about it than I do.

This is nothing that you would get with a simple click in the admin  
frontend but it is certainly configurable.

The Kolab Server uses postfix as MTA and amavisd-new for  
virus/attachment checking. Both might be used to impose limits on the  
message size. How the exact configuration might look like depends on  
your exact requirements though. "restrict users from sending"  
attachments is still a little bit vague. What exactly is an  
"attachment" in a multi-mime-part message? Does the HTML part a client  
might send already count as attachment or not? In general my feeling  
is that it makes sense to impose restrictions on the complete message  
size in that case. And that is something you could add to the postfix  
configuration. And I believe it should also be no problem to restrict  
that to a specific group of users.

Cheers,

Gunnar
