How to Perform Gray Testing for KumoMTA Shaping Rules?

get-help
1

After configuring KumoMTA, how can I perform a gradual rollout (gray testing)? For example, if I have set up shaping.toml for qq.com, how can I conduct large-scale simulated testing to verify whether KumoMTA applies the shaping rules correctly? Since it’s not feasible to directly test against real qq.com mailboxes, are there any recommended simulation methods?

You should be able to add domains and set thresholds to simulate bounce and transfail rates.
