In other words, leave the default recipient limit in place, it is
helping you to send fewer messages to the list by batching multiple
recipients in a single delivery. The rate limits are working
exactly as documented. You're just not understanding your logs.
If you think you need to rate limit recipients rather than messages,
please explain why that would be wise. Typically, such a goal is
the result of some sort of misunderstanding or confusion.
