Let's say I've got a mailing list of a million working email addresses, and I find a server that accepts all email before checking for invalid users. Let's also say that server bounces the whole message and not just the headers like some do. Instead of spamming the users directly, I can send my spam FROM those million users to invalid accounts at the mail server that bounces them. That mail server accepts the mail then sends my spam to the people I intended as a Mail Delivery Error, which people *ARE* likely to look at because they think they sent a mail that bounced. There are two things that NO mail servers should ever do: #1 - send responses to virus emails #2 - accept mail for unknown users and then bounce. If you're running a server that is being abused the way I described above, then your server deserves to be blacklisted.
