Hello, Thanks for this answer, my problem is I'm on yunohost server and the update 3.3.9 is not available now. Any "handmaid" solution should be great.
It may be more disruptive than you want, but you can just set DMARC Mitigate unconditionally to Yes to apply DMARC mitigations to all list mail.
Another thing which helped me a lot with Gmail bounces was setting VERP options everywhere in Mailman. I'm not sure what has made more of a difference, setting the DMARC to unconditionally apply the mitigations or setting VERP everywhere.
Speaking of the new additions in Mailman 3.3.9, does anyone have a list of the domains Google are using which we can add to the list so we can disable the unconditional DMARC mitigations for all list posts? Its probably somewhere obvious on a Gitlab issue or similar, but haven't found it yet.
Thanks. Andrew.
