You can control the initial grey listing time. I believe by default
they have 30 minutes. However I have seen no change in results of using
as little as 2 minutes.
The actual delay of the email however is going to be controlled by the
sending MTA. Based on log file examination most legit MTAs will retry a
message in the first 5 to 10 minutes. I believe sendmail retries fairly
quickly and then has an algorithm that backs off using longer delays
between retries until the message finally is considered undeliverable.
