Noel Jones:
Postfix does not have any controls for delaying mail.
You might be able to hack something together with some scripts using
the postsuper hold/release functions.
http://www.postfix.org/postsuper.1.html
Postfix provides per-destination rate limits, not per-message delays.
http://www.postfix.org/postconf.5.html#transport_destination_rate_delay
Example: smtp_destination_rate_delay = 600

That allows one message to that destination every 10 minutes, not
delivery after 10 minutes.
So the delays will be longer than what he wants if there are more than 1
messages per 10 minutes received per destination, and shorter than he
wants if there are less.
Just to inform the OP that it's probably not his solution without
further tweaking.
Of course, we don't know why this is deemed necessary - his real problem
may be easily solvable using other means.
