How Do I restrict domain admin access to mail only?

[FreetimersS]

I'm using Plesk 9.5 on CentOS Linux 5.5 with 130 or so domains hosted upon it.

I have created domain administrators for a couple of domains on this shared server. I cannot find any way to restrict domain admin access to mail accounts ONLY. I don't want my customer to access either file manager (which is pretty much an FTP access) or DNS. They should only be permitted to see mail accounts (create, change passwords, etc) and WebStats.

Is there a way to do this?

(I realise this is a bone of contention but is this possible in Plesk 10 at all?)

Thanks
