[BlueOnyx:02615] IMAP quota

[User Ernie]

I have just been playing around with the standard Macintosh Mail progam
talking to a BlueQnyx server, and I noticed that the program has the ability
to display how much of your IMAP mailbox quota you have used up but the
Capacity % display is n/a, and there is a comment that say "This account doesn't
support quotas" so I presume BlueOnyx is not sending the required IMAP quota info. 

Is there something on the BlueOnyx server I need to enable IMAP quota
support, or is it just a Mac Mail client issue?
