You'll have to use a combination of
/etc/postfix/main.cf:
slow_destination_rate_delay=x (this forces concurrency == 1)
slow_destination_recipient_limit=y
/etc/postfix/master.cf:
slow unix - - n - - smtp
-o smtp_connection_cache_on_demand=no
that stays within the stated limits (which of course may not bear
any relationship to reality, but that is a different matter).
And these clowns will have to get used to abnormal email delays.
I hope this isn't my tax money at work.
