DMARC, Gmail and Groups
DMARC, Gmail and Groups
Hi.
I have a group that includes some Gmail addresses and other private ones.
One of the private addresses sent an email to the group and for all the Gmail addreses I received an email:
Mail Forward Failure
The following message could not be forwarded to
user@gmail.com for
user@domain-on-zoho-with-group.com
Technical details of the failure:
5.7.1 Unauthenticated email from sending-domain.com is not accepted due to
5.7.1 domain's DMARC policy. Please contact the administrator of
5.7.1 sending-domain.com domain if this was a legitimate mail. Please visit
5.7.1
https://support.google.com/mail/answer/2451690 to learn about the
5.7.1 DMARC initiative. 2si3297364ots.275 - gsmtp
Should I make some tweaks on the domain hosted on Zoho? Or is it a Gmail or sending-domain's issue? Thanks.
