To even out the load, you can try tweaking these options: deliver_queue_load_max = 2.00 queue_only_load = 1.50 remote_max_parallel = 16 That will not grant for x mails processed per unit of time, but it helps to even out the spikes by delaying the processing if needed. It's probably much better than limiting to handling x mails per unit of time because it allows the servers to operate at full throttle without being overwhelmed by the amount of mail to handle, provided that you use reasonable values adapted to the performance of your servers. If that doesn't suffice, you will need faster or more servers anyway.
