Have a look at retry section?
# This single retry rule applies to all domains and all errors. It specifies
# retries every 15 minutes for 2 hours, then increasing retry intervals,
# starting at 1 hour and increasing each time by a factor of 1.5, up to 16
# hours, then retries every 6 hours until 4 days have passed since the first
# failed delivery.
# Address or Domain Error Retries
# ----------------- ----- -------
* * F,2h,5m; G,16h,1h,1.5; F,4d,6h
