Need help with setting up the server and configurations (first time working with KumoMTA)

KumoMTA Installation
1

Hi,

I heard great things about KumoMTA and wanted to try it. I usually work with PowerMTA, where it has a single config file and the process is straight forward. Now I intend to work with KumoMTA (tried on Ubuntu 22.04, and Almalinux 9), I am facing difficulties in configuring the server. I am either getting configuration validation errors or SMTP errors like “Service not available, closing transmission channel. The server response was: 4.3.0 mta.domain.com technical difficulties”

This might have already addressed, but I couldn’t find any direct reference to work with configurations.

I am new to Lua scripting and might be so used to work with PMTA, I am not able to get the things done correctly. Could someone please help me by guiding to a straight forward config like (init.lua, sources.toml, listener_domains.toml, queues.toml, etc.) or any tutorial other than the official docs.

Thanks in advance.

Regards,
Satyam

Have you worked through the tutorial? It walks through a working config.

In any case, we need your full set of configs and logs to provide any kind of support.
