> How to delete a message? once a message is sent and received, it is impossible to delete - it "happened"; and past events can not be altered - when the message is delivered (usually immediately) the receiver has received it, and probably has read it within seconds - so deleting chat messages is pointless, in all normal circumstances
that is not specific to jami - it is fundamentally true for all libre communications software - some may have such a feature, which appears to delete messages; but is never sincere - it is always an illusion, which can be exposed by the receiver (or a "MITM" observer, if the message is not encrypted properly) only non-free software could have a reliable deletion feature - it still would be an illusion; but because it is non-free, it would be very difficult for a user to remove that illusion the important thing to remember, is that a deletion feature is not very useful anyways; because, the message has usually been read by the receiver, within seconds of receiving it - so, not only is there no point in deleting messages, there is no point in keeping them either - the time window of relevance for any chat message is very narrow - in all normal use-cases, chat needs no storage - all messages may live only "on-the-wire", perhaps cached, but only for re-tries of failed deliveries if the message was important or has a longer time window of relevance, then synchronous communication such as chat, is not the right tool for the job - asynchronous communication with permanent storage (such as email or web forum), are much more appropriate
