Hello, The Telegram protocol and clients have a feature to shown to the sender when the receiver has read the message, Telegram Support calls this "read" status for messages and says it is an essential feature of Telegram. I call it a violation of the receivers privacy. I have an Ubuntu based mobile which has a Telegram app. We have had a long chat which can be seen here in issue tracker: https://bugs.launchpad.net/bugs/1475915 and both, Telegran Task Force and Canonical, are rejecting to make the read status report at least a configure value and any receiver can decide by its own to enable this or not. Related to this is as well the RFC 3798, which says: 6.2. Privacy Another dimension of security is privacy. There may be cases in which a message recipient does not wish the disposition of messages addressed to him to be known, or is concerned that the sending of MDNs may reveal other sensitive information (e.g., when the message was read). In this situation, it is acceptable for the MUA to issue "denied" MDNs or to silently ignore requests for MDNs. ... For the above mentioned reasons, I have de-installed the Telegram app on my mobile phone. Why I bring this up here? It would be nice, if we (FreeBSD) could add (as a patch in the ports tree) a configuration value to the telegram-cli which does not send such notifications when the configuration says so. What do you (all and Maintainer) think about? matthias -- Matthias Apitz, ✉ guru@unixarea.de, http://www.unixarea.de/ ☎ +49-176-38902045 No! Nein! ¡No! Όχι! -- Ευχαριστούμε!
