I’m missing few email alerts, got Nigelalder’s but not your last few including the 18:16.
OK we will have to monitor that. No idea how or why that can happen. In a sense an email cannot go missing ever (as it gets delivered back). So only assumption is it was never sent. No idea why that should happen, unless come to think of it, it has some anti spam built in and hence will not deliver 2 emails from the same person in the same minute?
