Implement MoveMessages in the imap backend. go-imap includes the MOVE Imap extension by default, and if a server does not support it the command fallsback to a copy-and-delete operation. Servers with the MOVE extension will see a slight performance increase when moving messages due to fewer round trips. The IMAP implementation uses a MessagesMoved worker message to avoid polling the destination mailbox. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
