I would love to see this as an option. I've had a couple issues sending to large corporate recipients where they email will be rejected for whatever reason... however, if the email is filtered to a spam/junk folder on the recipient's end, I receive no notification that there was an issue.
It's a great option for business use, because it helps me know if follow-up phone calls or emails are going to annoy my customer or if they just hadn't seen the email i sent.
