 #### Message Manipulation
 
 Beyond just flagging, you may move or copy messages between folders, as well as delete them:
 
-- `$message->restore()`: Restores the message from the trash.
-- `$message->copy(string $folder)`: Copies the message to the specified folder.
-- `$message->move(string $folder, bool $expunge = false)`: Moves the message to the specified folder.
-- `$message->delete(bool $expunge = false)`: Marks the message as deleted and, if desired, expunges it from the folder.
+- `$message->restore(): void`: Restores the message from the trash.
