I add an SPF entry on my web hosting, domain name: "v=spf1 mx ptr include:_spf.google.com -all" and it seems to fix the problem.
Smart. As I understand above statement, it allows the google servers to send out emails for your domain. Not sure you want that. But you're right, mailman will eventually pick up the -all for the google addresses and apply the DMARC mitigation to google originating messages. Is this assumption correct?
Wrong. Mailman in conditionally applying DMARC mitigations considers only the DMARC policy if any of the From: domain. Whether or not an outgoing message might be rejected for DMARC policy or any other reasons has no automatic effect on the application of DMARC mitigations to subsequent messages.
