You **can't** alter an existing UID message.  You have to re-add the  
message to the mailbox and use a new UID.  For this, you have 2 options:

1.) FETCH the message, alter it locally, APPEND the message to the  
server, and DELETE the original message.
2.) Use CATENATE to create a new message, and DELETE the original  
message (this is how we strip attachments from a message).  Note that  
not all IMAP4rev1 servers support CATENATE.
