I need to run a, secure, e2e instant messaging server for a small group of people (< 10).

The requirements are:

* iOS / Android client with push notifications
* Linux & BSD clients
* on-prem private server

What do people recommend?

[Edited to explain I want to run it on-prem for a closed group of people - sysadmins actually on a delicate project]

@cynicalsecurity have you considered setting up your own private non-federated matrix host?

@jmovs Yes, was looking at that…

@cynicalsecurity @jmovs matrix does not have proper e2ee for all situations unfortunately. Delta might be one of the few options next to more niche things. Not much actual MLS out there yet either unfortunately, give it a few more .. years
