That's interesting. Mail.app has historically (7+ years) sent CREATE +  
SUBSCRIBE. Going by just:
"The SUBSCRIBE command adds the specified mailbox name to the server's  
set of "active" or "subscribed" mailboxes as returned by the LSUB  
command."

I can see why a new client-created mailbox wouldn't want be to  
interpreted as "inactive." There are also some clients (I can't  
remember exactly which: one or more of Outlook, Entourage, or  
Thunderbird) that only show subscribed mailboxes by default in the UI.

Thanks for the clarification of the original intent.
