I recall that system-effing-d has a rare-limiting feature that very helpfully drops Postfix logging. Here's one search result with suggestions for systemd. https://www.rootusers.com/how-to-change-log-rate-limiting-in-linux/ Another search result: systemd and rsyslog both have rate limits. https://support.asperasoft.com/hc/en-us/articles/216128628-How-to-disable-rsyslog-rate-limiting It is time to update the Postfix page on LINUX logging brain damage.
