Tim Culverhouse 64e1a7ca93 imap: implement MoveMessages handling
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.
