Spoofing mozilla email?

Greetings to everyone.

Everytime a mail arrives in my inbox that comes from lists.mozilla.org, my email provider says something like “This email has failed its domain’s authentication requirements. It may be spoofed or improperly forwarded!” so I think, basing on https://protonmail.com/support/knowledge-base/anti-spoofing/ this article, it has failed DMARC check.

Could you please investigate more? It is a little bit annoying!

(also not sure if it is the right section, however I chose this one because the mail I am talking about it is about reps call)

Hi, is this a problem regarding the reps-general mailing list?
In that case, could you forward the email to me?

Thank you :slight_smile:
