Handle of "subscription" file/folder for IMAP

[Jorge Bastos]

Hi,

For IMAP users, there's the subscription file in the user's home, and if I
try to subscribe more imap folders that are invisible, there's that one, but
as it is a file, nothing is supposed to happen.
Is there an way to, allow users to create the "subscriptions" folder without
any collision, or just deny or don't show this file as an possible folder
(which Is not) to subscribe.

What does people normally do?

Thanks in advanced,
