Please forgive my ignorance, as I am not familiar with Lua. I used the following files: init.lua, dkim.lua, and tls.lua.
init.lua (503 Bytes)
tls.lua (251 Bytes)
dkim.lua (262 Bytes)
Where are you getting any of this from? AI or something? Some of what’s in these files do not even exist. Do not use AI, read the documentation. I don’t see what the purpose of “TLS” is in your examples, but you don’t set up TLS if you’re sending outbound mail.
I would recommend following the User Guide and using the DKIM and shaping helpers. They both already have what you need.

You can also see why kumo might not be starting by looking at journalctl -f -u kumomta.service
There’s also this talking about both Inbound and Outbound TLS in the documentation

Thank you, I appreciate your help.
