[opendmarc-users] Trusting/ignoring redirects from gmail servers

[Simon B]

Hallo,

I have tried to solve this on my own, but I am not able to.

Several users have gmail accounts configured to forward emails
accounts on the server.

99% of these emails go through, but I - and they gmail account - both
get a failure report, on the original sender.

For example.

------------------------------------------------------------------------

This is an authentication failure report for an email message received from IP
2607:f8b0:4864:3b::2b on Fri,  2 Oct 2026 07:58:06 +0000 (UTC).


Feedback-Type: auth-failure
Version: 1
User-Agent: OpenDMARC-Filter/1.4.2
Auth-Failure: dmarc
Authentication-Results: OpenDMARC.spamfreeisp.net; dmarc=fail
header.from=nvidia.com
Original-Envelope-Id: 4hx1Nr6WBDz1GDSd
Original-Mail-From: xxxx at gmail.com
Source-IP: 2607:f8b0:4864:3b::2b (mail-pz2-x2b.google.com)
Reported-Domain: nvidia.com

------------------------------------------------------------------------

How can I limit the checking / reporting to just gmail/google?

Thanks.
