I was under the impression that attaching business return mail to another package didn&#x27;t work any more - it&#x27;d obviously be an easy loophole to close.<p>Completely agree with the rest of the approach though. The real question is what to do with the &quot;broadcast&quot; flyers the post office has gotten involved in spamming. Stamp &quot;return to sender&quot; and stuff in blue mailbox? I don&#x27;t see that employee frustration adding up to any change.
