docker compose -f /opt/mailcow-dockerized/docker-compose.yml exec postfix-mailcow postsuper -r ALL

postsuper -r ALL resets the arrival time of all queued messages so Postfix retries them on the next queue run. Useful after fixing an outage that caused mass deferrals. It does not delete anything, unlike postsuper -d ALL.
