Matrix Synapse Certificates
I’ve had a need to set up and run a Matrix homeserver and I wanted to try to set it up for general use as well as just for this project.
The one thing I wanted to do that is a little non-standard is to use the “plain” domain for my user ID while hosting the homeserver on a subdomain. In this case I wanted to use “irl.xyz” as the user ID domain, and “syn.irl.xyz” to host the Synapse homeserver.
