INTERNALDATE is stored in message's mtime with maildir. It's preserved when COPYing a message to another mailbox. Whether it's preserved when a client copies it between different IMAP accounts depends on the client - APPEND command anyway supports INTERNALDATE parameter. Evolution's "Received" field means the same as INTERNALDATE and I always use it to order my messages. Works fine.
