that is when Anvil checks the logs… every minute. At least I think so. Yup anvil_rate_time_unit (default: 60s) The time unit over which client connection rates and other rates are calculated. http://www.postfix.org/postconf.5.html -ANGELO FAZZINA ITS Service Manager: Spam and Virus Prevention Mass Mailing G Suite/Gmail ang...@uconn.edu University of Connecticut, ITS, SSG, Server Systems 860-486-9075 From: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> On Behalf Of Paul Martin Sent: Wednesday, June 20, 2018 11:27 AM To: Postfix users <postfix-users@postfix.org> Subject: Re: 5 messages per second Thanks all, I would like a smtp client to send to my postfix only 5 messages per second.

Postfix does not have sub-second rate limit, and the support that it has will result in one message delivery at a time. Thus, you are limited to, for example, smtp_transport_rate_delay=1 or larger. It is not designed for sending lots of email. > How can I do that with postfix ? Maybe with kernel-level traffic shaping, or using some outbound proxy? Wietse
