Yo, check it out! Stalwart's comin' in hot with their slick new mail server that's about to shake things up. This bad boy's got it all - we're talkin' IMAP, JMAP, POP3, and SMTP support, plus a whole bunch of cutting-edge features that'll make your head spin. Let's break it down, shall we? This open-source beast is written in Rust, which means it's faster than a New York minute and tougher than a two-dollar steak. It's designed to be secure, speedy, and scalable - perfect for those of you who need a mail server that can handle the heat. Now, let's dive into the nitty-gritty. Stalwart's got full compliance with JMAP Core and JMAP Mail, plus a bunch of nifty extensions like JMAP for Sieve Scripts and JMAP for WebSocket. It's like they've thought of everything! But wait, there's more! The IMAP4 and POP3 servers come loaded with all the bells and whistles you could want. And don't even get me started on the SMTP server - it's got built-in support for all those fancy authentication protocols like DMARC, DKIM, and SPF. Plus, it's rockin' some serious transport security with DANE and MTA-STS. Now, let's talk spam and phishing protection. Stalwart's got your back with a comprehensive set of filtering rules, a statistical spam classifier, and even phishing protection against those sneaky homographic URL attacks. It's like having a bouncer for your inbox! But here's where it gets really cool - this thing is flexible as all get-out. It's got pluggable storage backends, clustering support, and even full-text search in 17 languages. You can authenticate with LDAP or SQL, and it's got support for all those funky email features like aliases and catch-all addresses. And if you're into that whole web-based administration thing, Stalwart's got you covered there too. You can manage accounts, domains, and mailing lists, plus there's a slick report visualization interface for all your DMARC and TLS-RPT needs. Last but not least, this thing is locked down tighter than Fort Knox. We're talking encryption at rest, automatic TLS certificate provisioning, and even two-factor authentication. Plus, it's been security audited, so you know it's the real deal. Bottom line? If you're in the market for a mail server that can do it all, Stalwart's the way to go. It's like the Swiss Army knife of mail servers - versatile, reliable, and ready for anything. So why not give it a spin and see what all the fuss is about? Trust me, your inbox will thank you!
