I realise this is probably not the time or the place but...

gah, I hate receipts. I regard them as an invasion of privacy. I don't want people knowing that I've seen their email they sent any more than I want them to know I'm call screening and I'm sitting by the phone and not answering it because I know who it is.

I might be in a bad mood or just be too busy to respond at that particular moment. The fact they now know I read the email and I haven't responded in the next 5 minutes means they'll probably call to find out why. Receipts are a bad idea and I was glad that Apple left them out by default. They are a rude, intrusive tool.

Still, if your workplace requires them, well now you have a way to use Mail at work and not be left out of urgent office communications like "Please wash your cups up after use, don't leave them for someone else".

Sorry. :)

I agree with lee_noble.

Return receipts are annoying, and it's good that Mail doesn't bother with them. Hopefully, Apple WON'T add a return-receipt option in new releases.
