After the arrest of Pavel Durov, I wanted to move from Telegram to something end-to-end encrypted. I know Signal is pretty good, but I think it is better to have our messages in my own server.
I have already looked in XMPP, but it required SSL certs and I did not have the mood to configure them.
Do you know any other selfhosted messaging service for a group of 4-5 friends, or an easy way to configure an XMPP server? Or shall I use Signal after all (I don’t really care that much about being selfhosted, I just thought it would be more privacy friendly)?
So long as your certs are for your fully qualified domain there’s no problem. I do this, as do many people — mydoman.com is fully qualified, but on my own network I override the DNS to the local address. Not a problem at all — DNS is tied to the hostname, not the IP.
