Tested and modified in MacOS 10.9 Mavericks: September 2 2014
This still works but you have to do all the steps before you can test it. Also
be aware that it is possible for the return receipt request to be seen before
the actual email, at least when testing it on myself. I've only tested it on
I've been working on this receipts issue and I'll try to lay out what I've
done. I am now able to request receipts, reply to a request for a receipt (only
tested on sending to myself), check to see if requesting receipts is turned on
and off, and turn requesting receipts on and off.
