One of the members on the Group I moderate has reported that email deliveries to him stopped earlier today. His delivery option is "Individual Emails", and a check of his email delivery history shows no bounces, and that messages are being successfully sent and delivered.? (i.e. 2.0.0. applies)
He has reported that email deliveries from other Groups.io groups are working normally, and that his ISP's? (Videotron) response is "nothing to do with us mate" or words to that effect. "Normal" emails to him work all right, although I haven't tried emailing him via Groups.io yet; that's next on the list.
Has anyone else here experienced anything similar, and if so what was the cause?
