Restricting Emails to Specific Domains with KumoMTA

Hi everyone,

I’m looking to block specific domains from being received by my KumoMTA setup. Specifically, I want to prevent any emails from being sent to or received from domains like example.com.

Could someone provide guidance on how to configure KumoMTA to block specific domains for recipients?

Thanks in advance for your help!

Look at How do I create an always-suspended queue? - KumoMTA Docs

But instead of a suspended pool you could set the queue to nil

or use kumo.reject to explicitly reject it
