Stalwart JMAP/IMAP Server

What it does

Stalwart JMAP is an open-source JSON Meta Application Protocol server designed to be secure, fast, robust and scalable. It also includes support for IMAP4 rev2/1.

Open-source mail and collaboration server with JMAP, IMAP4, POP3, SMTP, CalDAV, CardDAV and WebDAV support. Written in Rust, designed to be secure, scalable, and easy to operate.

One server for your email, calendars, contacts and shared files, with spam and phishing protection built in. Every standard protocol your clients already speak (JMAP, IMAP, POP3, SMTP, CalDAV, CardDAV and WebDAV) supported natively. Compatible with every email client your users already have. Modern JMAP for new apps, full IMAP and POP3 for everything else, and SMTP for delivery. Calendars, contacts and shared files in the same server as the mail. Standard CalDAV, CardDAV and WebDAV for existing clients, and the modern JMAP equivalents for new ones. Spam and phishing handled before messages reach the user. A statistical filter, public blocklists, sender reputation and AI-driven analysis,…from stalw.art

  This is ymawky, a static file web server for MacOS written entirely in ARM64 assembly. It supports GET, PUT, DELETE, HEAD, and OPTIONS requests, and supports Range: bytes=X-Y headers (which allows scrubbing for video streaming). It decodes percent-encoded URLs, strictly enforces docroot, serves custom error pages for any HTTP error response, supports directory listing, and has (some) mitigations against slowloris-like attacks. I’ve also written a more detailed writeup here: https://imtomt.github.io/ymawky/

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
