This doesn't quite make sense, because 4xx isn't a bounce. It's a delay code 
to your mail server to try again later.

sendmail, by default, generates a warning back to the sender if it hasn't 
been able to deliver it for 4 hours, and that notice MIGHT be interpreted as 
a bounce, but that's the only thing I could think of.
