Hello, This is my first reply/post ever, I hope it helps. A way to reproduce would be to use your own gmail address to send email to your server, block your email address in the incoming rules of the server while assigning a 5xx code to it, send the message from gmail and wait for a bounce back. Also check the log on your server.
