We have been using Google Legacy our for company emails & recently emails sent to group emails e.g email@example.com, have been bouncing back with the below message:
The response was:
Your email to group firstname.lastname@example.org was rejected due to spam classification. The owner of the group can choose to enable message moderation instead of bouncing these emails. More information can be found here: https://support.google.com/a/answer/168383.
As the admin I have followed the steps provided by Google but I have been unsuccessful.
Any suggestion on how I can solve this issue?
