Re: Members Unable to Post to Group
One member of my group said that her email to our group bounced, so IAs Duane and others mentioned, the Email Delivery History is for outbound messages - from the group to the member.
It sounds like your member's message bounced on the inbound leg - from her to the group's posting address. You can learn about problems on the inbound leg from the group's Activity log. In the Message Activity tab look for entries showing "attempted to send message". Those will be failed attempts,
But it sounds like you already figured out that this was a case of
"Non-member [person's gmail address] attempted to send message ..."
