How do I determine if a sent message had a return receipt request attached?
I don't always send return receipt requests with messages so I'm wondering how I can tell if I sent an RRR with a particular sent message? If I sent to multiple recipients, I'd like to know who has not returned a receipt.

You might be able to use a Message Filter to tag the ones that have a receipt requested. I haven't tried that with Sent Items, but tested something similar for incoming messages in this thread: https://support.mozilla.org/questions/1003321
