Mail.app and IMAP Unsubscribe

[LuKreme]

OK, I know I've looked into this once before, and the answer then was  
no.  Hoping for some change though.

Is there anyway to force mail.app to unsubscribe from some mailboxes  
on the IMAP server?  I mean, I don't need 2001-2006 mail accessible  
all the time, but I want it there so that I _CAN_ access it ont hose  
rare occasions I need to.

For example, whilst in mexico last month, I needed to scan 2002-2005  
emails looking for some contact information, so I am loathe to take  
that offline, but on the other hand, I don't need to have access to  
it every day all day.
