No, but you can control the delay between successive deliveries. http://www.postfix.org/postconf.5.html#transport_destination_rate_delay http://www.postfix.org/postconf.5.html#default_destination_rate_delay Caution: the resulting behavior depends on the value of the corresponding per-destination recipient limit. If you set the per-destination recipient limit equal to 1, you will send too much email. - With a corresponding per-destination recipient limit > 1, the rate delay specifies the time between deliveries to the same domain. Different domains are delivered in parallel, subject to the process limits specified in master.cf. - With a corresponding per-destination recipient limit equal to 1, the rate delay specifies the time between deliveries to the same recipient. Different recipients are delivered in parallel, subject to the process limits specified in master.cf. Wietse
