Note, editing main.cf is not sufficient. The change requires
"postfix reload" (or stopping and starting Postfix).
If default_destination_rate_delay=10s does do the job, then
smtp_destination_rate_delay won't either. The difference is that
default_destination_rate_delay also affects local deliveries,
which is rarely needed.
