You need to keep the following in mind, if you ever decide to use
a per-destination recipient of 1.
Wietse
default_destination_rate_delay (default: 0s)
The default amount of delay that is inserted between individual deliv-
eries to the same destination; the resulting behavior depends on the
value of the corresponding per-destination recipient limit.
o With a corresponding per-destination recipient limit > 1, the
rate delay specifies the time between deliveries to the same
domain. Different domains are delivered in parallel, subject to
the process limits specified in master.cf.
o With a corresponding per-destination recipient limit equal to 1,
the rate delay specifies the time between deliveries to the same
recipient. Different recipients are delivered in parallel, sub-
ject to the process limits specified in master.cf.
