The answer depends on information you have not provided.
* How is this client distinguished from other clients?
* How big (message count) are the mail "bursts" from this sender?
* At what rate are messages arriving during a "burst"?
* How many such bursts a day?
When you slow down mail delivery below the burst arrival rate, a backlog
develops somewhere along the pipeline. Depending on the size of the bursts,
the choice of the right place to buffer the bursts may change.
