I am not opposed of smarthosts, they are a good thing because they make it possible to do spam checks for outgoing mail and they also make it easier to keep track of mail flow. > Making the argument that there should never be bounces is silly. Bounces are so fundamental to email that we can never get rid of them, but they are very problematic and risky when they are sent across organisation boundaries. If someone insists on sending bounces because of forged recipients or full mailboxes, they should be prepared to accept the problems that will eventually arise from them.
