"The blacklist works by sending an SMTP 550 error code, which indicates that the requested mailbox does not exist"
Really? The message actually says that the mailbox does not exist, rather than giving the real reason the message was rejected? That would be particularly
silly, if it's true.
SMTP rejection messages contain free-form text after the error code, which should always be visible to the user when they receive a bounce message. The spam-bots will only care that the message was rejected; real users should see the message, and it should be meaningful.
