I am not receiving certain emails from entertainment venues [booking confirmation, eticket.] I get other emails from the venues in question including more general ones that indicate they've received my order, and I've been able to collect tickets at the box office without a problem. I've queried this with the venues concerned and they've re-sent the messages but still without success. The mails are not being delivered to my Junk folder, and previous ticket messages from them have always reached me, as they continue to do from other venues. The theatre and the [unrelated] gallery in question can't suggest what's amiss: I can locate the bookings in my online account with each, but where are my messages going?
