[MM3-users] Re: mailman3 auto-disabling of subscriptions

Your issue is mail From: the gmail.com domain to the list and sent to gmail users is being bounced because it fails DMARC. I.e. Gmail applies a DMARC policy of p=reject to mail From: gmail.com even though it's published DMARC policy is p=none.

Gmail's DSN is so badly worded it's not clear to me *what* it's supposed to mean.

I wonder if enabling ARC might not help with getting things through to Gmail. Google was very supportive of the ARC effort.

You need to apply DMARC mitigations to this mail.

I agree this is the most straightforward approach.
