No, but a modern server (typically >= 16 gigabytes of RAM) can have a much
larger active queue than the default. With a larger active queue, you can
absorb larger bursts of mail without saturating the active queue. Otherwise,
indeed you can rate limit mail for a particular destination via a policy
service or similar and push the issue upstream...
