It's apparently needed for "legacy" and the new MatrixRTC calls on Matrix

They only seem to support it for business customers for now, not for consumer usage.

I live in a rural area, so my only options are dealing with a mobile hotspot for everything or getting satellite internet for more than double the price.

It's also not worth it for me to switch internet providers just to have calls on my Matrix server work

Unfortunately my ISP doesn't support IPv6 yet, both for the public internet and for my local network.

I'm in the same situation, I can do "legacy" calls almost without issues, but Livekit has constant issues connecting to TURN.

Oops, autocorrect seems to have messed up some of my words. All of the clients that connect to the servers are behind the same NATted network, and some are behind an additional level of NAT.

I've been trying out Stalwart, and it seems to be working good, but it is having problems with IDN that seem to require some weird ways of fixing.

(more specifically, Stalwart recognizes the punycode and UTF8 versions of domains as separate, which is difficult for some clients like Gmail web to deal with)

So I've been setting up Stalwart (but I probably won't be using it), and I only had to unflag my emails as spam on Gmail and Outlook once; it even was able to send straight to the inbox of another Gmail account! I did have one email get quarantined by Outlook, but it was probably because the email and sender name didn't match enough.

I use both. I have one VM on Proxmox for all of my Docker containers, a seperate VM as a reverse proxy, and a third VM to handle OIDC for apps (because I don't want it failing with all of my other things). I also use Proxmox for using apps in a VM that are GUI based, but that I want to have running on something other than my laptop.
