how to disable selected mailboxes ?

[J Desrochers]

Hello,

We are currently using Cyrus 2.2.12 on RHEL4.1 for a couple of weeks.
Now i need to temporarily DISABLE some active mailboxes. by disabling i 
mean,
server must reject mail coming to this mailbox and i must prevent user from
accessing is own mailbox.

Is there a way  i can disable some accounts (without loosing data) and
then re-enable selected accounts (imap commands?)

Regards,


Jerome
