TL;DR
- Users who have rooted their phone, have their bootloader unlocked or are using some custom ROMs report that their RCS messages are not being sent, even though RCS shows them as connected.
- The Google Messages app does not show any error messages when blocking RCS messages of these users and does not send the messages out as SMS or MMS either.
- Google famously campaigned for Apple to include RCS messaging in iMessage but is now blocking it for certain Android users.
XMPP + OMEMO
also matrix
That too, but it is more resource-hungry to host (my biggest problem is that I have very limited storage and haven’t quite figured out how to disable media downloads from all rooms). But yea, indeed still an option.
In worst case, symlink image folder to /dev/null.
I think the conduite server should be very lightweight, secure and easy to set up. But it’s leaking video
Yea, Synapse was out of the question for my low-power VPS, so I was going to try either this one or Dendrite. Just that last time I looked, I did not resolve the storage concerns. Ideally, I would like to not save any media and text that comes from federated servers.
Needs to be something like family is going to use you see. Which is why I liked what Signal had since it doubled as SMS.
Messaging layer security exists now, just a matter of implementing it for xmpp
Great example since Google essentially hijacked XMPP and took it into a fully-intentional nosedive.
