Postfix doesn't have any per-user rate controls (some add-on
policy services can do per-user input rate limits), and output
rate controls are limited to what's available with
http://www.postfix.org/postconf.5.html#default_destination_rate_delay
which is a per-destination limit, not an overall limit.
You could put all those messages on hold and release them
after hours. man postsuper; man cron
Maybe router or firewall based traffic shaping would help - at
least you could prevent SMTP from hogging all the bandwidth.
