rit can be used to manipulate mailboxes over IMAP, allowing users to copy and delete mailboxes and their contents. When copying a mailbox, its subscription status and all of the IMAP flags of the messages it contains are preserved on the destination server. Dynamic mailbox name translation can be performed if the mailboxes need to be renamed as they are copied.
