Of course. The problem arises when a spammer uses one sender address to
send hundreds of thousands of emails to thousands of servers each of which
sends autoresponses of some sort. It's not just mailing lists that are a
problem here, there are all sorts of DSNs, vacation messages and so on.

Yes, they're useful. But they're harmful, too - unless you're certain that
they're going to a legit sender. Usually, they're not.
