Captive mailbox in Cyrus IMAP?

[cyrus-admin at spiresfamily.com]

I could see this being useful as well for password expirations.  When the 
password expires, trigger it to display only the message explaining that the 
user needs to go to the web portal and change their password.

Unless there are better ways to force password changes for IMAP/POP dominate 
users, I've been wrestling with a solution to this for a while now.
