Hello Proxmox Community,

We're currently working on enhancing our email security and would like to implement a rule or mechanism within our Proxmox Mail Gateway setup to quarantine emails from senders who do not have published DMARC records.

Unfortunately, we're unable to open a support ticket at this time, so we're reaching out here for community guidance.

Has anyone successfully implemented such a rule? If so:

  • What approach or configuration did you use?
  • Are there any recommended best practices or caveats to be aware of?
  • Would this be best handled via custom rules, or is there a built-in feature that supports this?
Any advice, examples, or documentation references would be greatly appreciated!

Thank you in advance for your help.

Best regards,

Scott
