A while ago I moved it to <a href="https://stalw.art" rel="noopener noreferrer">Stalwart Mail Server</a>, which handles mail, calendars, contacts, Sieve filters and file storage in a single binary. It also speaks <a href="https://jmap.io" rel="noopener noreferrer">JMAP</a>, the JSON-over-HTTP protocol for mail.</p> <p>So I wrote a browser client that uses all of that. It's called <strong>ihasmail</strong>. It's AGPL-3.0, it runs as one container in front of your Stalwart server, and it has a <a href="https://demo.ihasmail.com" rel="noopener noreferrer">live demo</a> with a made-up mailbox behind it. There's no sign-up, and nothing you do there is kept.</p> <ul> <li>🌐 <a href="https://ihasmail.org" rel="noopener noreferrer">ihasmail.org</a>: what it is and what it looks like</li> <li>📘 <a href="https://docs.ihasmail.org" rel="noopener noreferrer">docs.ihasmail.org</a>: installing, configuring, using it</li> <li>💻 <a href="https://github.com/Coffey-Labs/ihasmail" rel="noopener noreferrer">github.com/Coffey-Labs/ihasmail</a> </li> </ul> opensource selfhosted webdev typescript
