It seem to me that when a user subscribed to an external Imap account via the Preferences->Accounts option in the web client, ZCS downloads all the remote messages via imap to local copies. That take a long time for the initial setup, specially if the user has a large remote mailbox and also it seems to be a waste of disk space.
Am I missing something? Is there a config option to make it stop?
