1- It will be received in 4 or 5 days. I only saw it because I have
access to the server logs. If I relayed via an external server, I
wouldn't see anything until 4/5 days. This in itself is bad.

2- now, if your challenge expires in 3 days, it gets dramatic...

3- also, if a spammer forges my address and sends via his ISP relay,
then I would get the bounce.
