Hadn’t heard of this before. I’ll give it a whirl.

Is *warden the new hotness? Bitwarden, vaultwarden, linkwarden and now certwarden?

I use my Roon sever to stream and group mine. Expensive to get into, but smooth enough to get partner approval for use.

I do. Run about a half dozen email servers for various organizations. Been doing it for almost a decade for some. Other than initial setup pain, I’ve had zero problems others describe. I have used (and still run) docker-mailserver, mailcow, mail-in-a-box and mailu. All are lovely in their own way and fit various use cases better than others.
