No, that limits the rate of incoming email. Exim does not support outgoing
rate control in any simple way. Essentially you have to use queue-only,
because the way Exim delivers messages immediately prevents it from doing
per-destination serialization. Then you can try using -qq to run the
queues to serialize deliveries for each host, or you can use a custom
queue runner, such as
