I recently transferred a group from Yahoo to groups.io. The transfer went well. Since then I have added one new subscriber. He was accepted. When he tries to post, i.e send a message to the group he receives?¡°groups.io rejected your message¡±.? I have set his profile for the groups default, everyone can post, and to allow him to post. Neither setting lets him send. Am I missing something I should set to allow him to send? No one else has yet complained about this limitation. Thanks for you help.
