Your issues with voice calls are likely because you didn't set them up, and the web client was using the fallback server.

Most of the names you can find by looking at the Git history of Element's repos - but that seems a bit stalkerish to people that have private lives to me.

On desktop? Yes. On Element X? Not yet. Requires additional setup, as it's not a core part of the homeserver

For spam protection, we use tools like meowlnir or draupnir with the cooperation of the homeserver to allow completely blocking spam invites - so if a matrix ID goes evil you can leave the room you have with them and add them to a ban list, and you can subscribe to a variety of other ban lists to ban things in advance

I'm pretty much sure only free option for finding out what other people search for is Google Trends. It's very valuable data that is hard to get, so the companies that offer it charge quite a lot for it.

If you have the time to set it up, Stalwart can manage its own cert renewal.

Where did you get this from?

Email is federated. You can set up your own server using something like Stalwart in a few hours. I deliver thousands of emails a month on my personal server. The problem is deliver ability to Gmail and outlook, but if you don't care about that then you're golden.

This isn't a password manager. It's an IdP

I host mail via Stalwart, which makes it pretty damn easy - it handles most everything, just giving you a big block of DNS records to upload with all the DKIM SPF MTA-STS nonsense. However, spam filtering from big providers is still occasionally an issue. I still occasionally get reports of mail making it into Gmail's spam inbox, for example.

You should! You don't have to be qualified to have something interesting to say - and you're doing it, so you know more than most people!

That sounds fun! Have you written about it?
