Absolutely not. I promise that each delivery to that destination (recipient or domain) will be followed by the per-destination transport_destination_rate_delay. > I think that this info - the delay between deliveries is per > connection and not per, or only, per domain - should be stated > clearly in the documentation. Absolutely not. I promise that each delivery to that destination (recipient or domain) will be followed by the per-destination transport_destination_rate_delay. Wietse
