Hi

We've been using Proxmox Mail Gateway for over two years now and everything is fine. Now, one problem appeared.

I have a WP Forminator tool that is deployed on a local infrastructure. He sends an email when the user completes the application.

Proxmox Mail Gateway block tihis email and show this
Picture in the appendix .....

How do I put this sender on the white list to receive the email?

You should configure the WP Forminator tool system to have a correctly resolvable hostname instead of `TEST-www.localdomain`
