Is there a way to set it up so user@example.com can be a lemmy account and also a mastadon account? I seen people using subdomains like user@lemmy.example.com and user@mastadon.example.com is this nessasary? Could u also set up a matrix account with the same user@example.com? If not what woukd be requured to change to make this possible?
Thank you for the very detailed explanation. I figured for services using a different protocal would be easyer as they can be handled almost independantly.
Would i need to modify the code of every services to man in the middle myself surly since i control the private key i can just do it after it leaves the service then if i pipe that back to my “universal” incoming it would distribute it to the relevent services?
I dont understand why the last approach breaks mastadon-lemmy interaction? It seems like the best solution if it wasnt for that.
If you do a perfect MitM (which is quite hard and requires constant modifications as software you’re MitMing updates) you wouldn’t need to change anything about the applications you’re running. I don’t think that’s very viable, though.
The way Webfinger works is that a remote server fetches details about the correct destination for messages once and then uses that to post a bunch of updates. If you tell every Lemmy server to post to user@lemmy.server, the Lemmy servers wouldn’t be able to post to user@mastodon.server.
