Hi Team,
We are using Proxmox Mail Gateway (PMG).
When emails bounce or fail to send, PMG sends a message from mailer-daemon@<hostname>.
The problem is that this email address is not allowed by our SPF/DMARC settings, so other servers sometimes reject it.
Is there a way to change the sender address for these bounce messages to use a different domain that passes SPF/DMARC?
We looked in the PMG web interface but couldn’t find where to change it.
Thank you!
