So something like a spammers dream... Let them know when the user has gotten their message. How to you limit to whom you send acknowledgements.
Were I to want this, I'd want it implemented in the MUA (the user's client). Watching a log file requires access to headers, which it doesn't have unless you just use certain domains to ack to. Then you have to watch out for acknowledgments of acknowledgments. Having qpopper do it requires non-standard extensions. Having the MTA do it doesn't work (every local delivery, including .forwards) triggeres a return receipt. I used to have a pretty good map of NeXT's internals thanks to getting 4-5 return receipts every time I sent a message. And I knew to whom their internal aliases sent. What you want may be non-standard for a reason :) Consensus may have shown that this is either non-wanted or even undesirable and perhaps you or your management are addressing a solution rather than re-addressing the problem. And do I *need* a 24 line pgp sig for a two line (prewrapping) message? Do we need to be able to verify who you are in a list question?
