Is there a way to uncover why 301 of these emails didn't send?
Customer is on 2018 so I'm suspicious of TLS being at play but usually I've seen that outright reject a send as opposed to rejecting a portion.
And in this case it doesn't seem like the process stopped. Only that many emails didn't go out.
