mod_password_policy: Change error type from 'cancel' to 'modify' This makes more sense, as the problem relates to the data that has been entered, and therefore the request could be retried with different data.

module:hook("message/host", function (event)
	local stanza = event.stanza;
	if #stanza.tags == 1 and stanza.tags[1].attr.xmlns == "http://jabber.org/protocol/chatstates" then
		return true;
	end
end, -10);
