Do people really send messages with a return path of 'noreply@example'?
Or, do you mean that people use a return path of 'noreply@<their own
domain>'?
With the former, I'd expect a large number of those messages to be
blocked/discarded (it's common to do call back verification, or just
simply check that the sender domain exists). I'd only expect that to be
done by people who don't really understand what's going on. I know we
have to deal with quite a few cases where our customers have errors or
missing messages, which turn out to be because they've misspelled the
domain part of their email address, and their mail is being
blocked/discarded because the return address is invalid.
