Gmail spoofing notification

MDaemon 18.52
Server 2016

I have tested the mailserver using dmarcian and all tests pass for DMARC, SPF, DKIM, yet, when listmembers send a post from gmail they receive a big yellow "possible spoofing" notification when they open their own posts. Does anyone have any experience with this and can suggest action that can resolve this behavior?
Thanks,
mux

Hello Jay,

This is likely due to the fact that when the message is sent from the mailing list, the �From� header contains the address of the sender�s Gmail account.� Since the message was received from a non-Gmail server, it might be perceived by Gmail as spoofed.
