Events into Kafka

Hi,

kumomta version: 2025.12.02-67ee9e96
running on kubernetes version 1.32
I’m struggling to get events into kafka, namely, bounce & fbl, I do have log_hooks successfully going to kafka, so I know the connection with kafka (inside k8s) is fine.

Here is my init.lua: init.lua · GitHub
this is my listener_domains.toml: listening_domains.toml · GitHub
this is my shaping.toml: shaping.toml · GitHub which, repeatedly logs an annoying (perhaps pertinent?) warning:2025-12-15T18:46:30.721478Z WARN spawned-task-kumo.tsa.config.monitor lua: /opt/kumomta/share/policy-extras/shaping.lua:54: Entry for domain 'kafka' consists of a single DNS label. Domain names in TOML sections need to be quoted like '["kafka.com"]` otherwise the '.' will create a nested table rather than being added to the domain name.
I have tried various things, including (yes, I am sorry) various AI slop hacks, some of which may have worked in places, but my current config results in routing errors as the queue can’t be resolved message.json · GitHub
I also had the same when the queue was just kafka if anyone has any hints as to where I’m going wrong, I’d be very grateful!
Thanks
Luke

I would change your kafka shaping domain to be the actual domain of the kafka server, or call it something like “kafka.local” and include mx_rollup = false.
