The point is, that even between trusted and identified person every side should be able to let the sender in the unsureness if the message arrived to his/her eyes or not. This is what privacy is called and which is violated by Telegram.matthias
I agree with Mathias, this conceptually is the same as in return receipts in ordinary email; it is a feature implemented by Mail User Agents, and every (serious) Mail User Agent permits the user to disable it.
If this feature is part of the Telegram protocol, the protocol itself is seriously broken, and in that case I will avoid at all Telegram usage.
MDNs (RFC 3798) are a formalization of "Return Receipts" , but exactly for the same privacy reasons Mathias refers to, "requests for MDNs are entirely advisory in nature - i.e. recipients are free to ignore such requests":
