<p>Two questions regarding delivery confirmation:</p><p> a)  Would allowing delivery confirmations to be returned to senders, am I saying 'yes' to receiving more spam?</p><p> </p><p>b)  How possible would it be to use filters, daemons, to have automatic delivery confirmations sent back to people that email my company (even when they do not use the delivery confirmation option in their email client)?</p><p>And maybe have like an opt-in opt-out for those automatic delivery confirmations? (list of sender's email addresses that request them).</p><p>thanks.</p><p>  </p>
