An MTA-STS (Mail Transfer Agent Strict Transport Security) policy is essential for securing your emails with both encryption and authentication. This helps prevent potential and malicious MITM (man-in-the-middle) attacks which involve interception and tampering during transit through SMTP (Simple Mail Transfer Protocol) used by mail providers. MTA-STS is a fairly new standard which makes email communication much more secure, and has been adopted by Google only a few years ago and Microsoft as of last year. If you have and use your own domain for email, you will need to create, configure, and publish your own MTA-STS policy.

You can create a Mastodon alias with your own custom domain without having to host your own Mastodon server, thanks to some web magic. It’s called an alias because it doesn’t change your actual address, but it’s very useful for identity and discoverability. This means that others can find you on Mastodon (or the wider fediverse) using your alias – a part of your identity that remains unchanged, even if you switch or migrate servers.
