Tellier Benoit created PROTOCOLS-109:
----------------------------------------

             Summary: Quota support for Append, copy and move IMAP commands
                 Key: PROTOCOLS-109
                 URL: https://issues.apache.org/jira/browse/PROTOCOLS-109
             Project: James Protocols
          Issue Type: New Feature
            Reporter: Tellier Benoit
            Assignee: Eric Charles


I think it would be nice to have IMAP command that may increase the size of a mailbox \
to check quotas.

I listed those commands : 

  - APPEND
  - COPY
  - MOVE

I already implemented some stuff in the COPY processor :
  - before copying anything, I check quotas
  - I compute the total size of the moved messages
  - I get the quota for the targetted mailbox
  - Check the quota by adding the total size of moved messages to the target mailbox \
                quota and check it.
  - If it is OK then messages are moved
  - If not, I think no message should be moved ( RFC 3501 : if it fails, nothing \
should have been done )

Something similar can be achieved with the move commands.

Problems appears with the Append command : we can not get the size of a stream, and I \
do not believe ( or even trust ) that the clients sends the size of the message with \
                the command... So there is two solutions :
  - Get the full message and calculates his size, and add it to the store if quotas \
                are OK
  - Normally append the message end check quota afterwards. Delete the messages if \
quotas are not OK. I think I would prefer this solution.

What do you think ?
