Some more design stuff:

It should be possible to i18n error messages from any method in the API.

For example, if I today try to create a mailbox which already exist, I get the 
following message displayed in the
Email client:

"Cannot create the folder. The server responded: 'CREATE processing failed'"

It does not tell me what is wrong and it gives me unimportant information.


The message should be generated with similar technique to what is available for 
subscribe():

   throw new 
SubscriptionException(HumanReadableTextKey.GENERIC_SUBSCRIPTION_FAILURE);

So for mailbox exist exception I would like to throw:

   throw new MailboxException(MyTextKey.MAILBOX_EXIST_CANNOT_CREATE);

and then i18n properties files to resolve:

mytexts.mailbox.exist.cannot.create=A mailbox with this name already exist, 
cannot create it!

Cheers,
Martin

Design: Consolidate Sessions
----------------------------

                 Key: IMAP-71
                 URL: https://issues.apache.org/jira/browse/IMAP-71
             Project: JAMES Imap
          Issue Type: Improvement
          Components: Mailbox, Protocol
    Affects Versions: 0.1
            Reporter: Robert Burrell Donkin
             Fix For: 0.1


ATM two sessions are used - an ImapSession for the IMAP protocol layers, and a 
MailboxSession for the mailbox layers. This is probably a mistake. The API 
would be easier to extend if protocol and mailbox used the same session. 

Unfortunately, ImapSession is coupled to a number of quite IMAP specific 
classes. Improvements to the design in this area (eg. simplification of the 
inefficient notification system) would probably allows this to be refactored 
but for the moment, seems better to push methods up into MailboxSession, and 
MailboxSession up into the API. ImapSession could then extend MailboxSession.
