It may also give them an incentive to change service providers.

One real reject and a later summary of several more rejections for the same
cause seems reliable enough (every sent message not delivered is accounted
for to the user). Dropping all of them on the floor or dropping the
"several more" on the floor doesn't, and wasn't what I said. The user is
still likely to be very confused (I don't have that address anywhere...yes
you do, it's in a page in your web cache...what's a web cache?...)

It's very true that I wouldn't expect your mail servers to be configured
this way. I (were I served by your servers) would probably appreciate your
way.
