The target mailbox of move_messages() should be something like
account1.archive (I guess this is what you meant).

I believe copy_messages() returns true or false based on whether the
IMAP COPY command (or the IMAP APPEND command when copying to a
different server) was successful.  You can check that easily:

	ret = results:copy_messages(account2.incoming)
	print(ret)
	if (ret)
	...
