Definitely I need to study this book. It is out of print now and I am getting  a used one soon. Thanks.
 
While I am reading the RFC 3501, come across one question about the mail's UID.
 
If the requirement for the client, which uses c-client, is to list all mails for each mailbox in UI in one connection. And store the mail's UID in local, later if user clicks on that mail, its UID will be used to fetch the mail's body. It could be done by doing mail_open(...) for each mailbox  one-by-one.
But seems there is problem for this approach.
 
in 2.3.1.1 Unique Identifier (UID) Message Attribute
It says:
"The unique identifier of a message MUST NOT change during the session, and SHOULD NOT change between sessions." 
It means the UID might change between sessions (true/false?).
 
So after select another mailbox, the previous opened mailbox's session is closed and the UID of the mail in previous mailbox might not be simply valid. Does it mean if user clicks one the mail, the client have to do
1. reselect the mailbox by mail_open(),
2. check the validity of the UIDs, (is there a function in c-client does this?)
3. use the adjusted/valid UID for fetching body?
 
Or is there a better approach with c-client?
 
Thanks for your help!
