Yeah, it basically seems that there are no native capabilities in Postfix for what I’m looking for, and so everyone pretty much needs to roll whatever ad hoc log monitoring they want. It’s a challenge because of the diversity of responses that MTAs can respond when there are problems with your servers. Error codes are helpful but not used in sufficiently standardized ways based on what I’ve seen in our logs.

Obviously the sooner I can catch these messages and act on them, the better, so the more realtime I can do this, the better. Random ideas: * Configure your syslog/rsyslog to copy logs to the pipe. Write a simple script that parses "status=" and sends you a message. There are alot of parsers like https://metacpan.org/pod/Mail::Log::Parse::Postfix * Use your network monitor tool if you have any. For Zabbix you could use https://github.com/aadz/mlogtail Zabbix can send you email/sms/slack message/what ever when "bounced" (or some other counter) increased
