Offline messaging is indeed a challenge on such distributed services that avoid any central servers. Currently messages are only cached for around 10 minutes in the DHT network before they are discarded. The way Jami currently handles delivery of such messages is to cache the message on the sender's device, and send it as soon the recipient of the message comes online. This ofcourse requires the sender to be online as much as possible. Beta testing is currently going on for group chats that will also provide a better solution for this - https://jami.net/swarm-introducing-a-new-generation-of-group-conversations/ https://jami.net/swarm-introducing-a-new-generation-of-group... ...
