I’m interested in setting up my own instances for Lemmy, Mastodon, and Matrix.
Can I use the same https://domain.tld for all of them without any subdomains?
For example:
lemmyuser@mydomain.tld
mastodonuser@mydomain.tld
matrixuser@mydomain.tld
Will this work across all of my self-hosted instances, or do I need to append a subdomain for each, e.g., lemmyuser@lemmy.mydomain.tld?
It will work for Matrix, because that’s what I got. Required some .wellknown-host magic if I remember correctly.
I don’t know if it’s possible for the other two. For Mastodon, in my case Akkoma, I went with social.mytld.com and lemmy.mytld.com for the Lemmy server I set up today.
