👋 Hey, it's a me, Mauro!

I’ve been passionate about coding since the early ’90s — my journey began in 1991 on the amazing Commodore 64. A couple of years later, in 1993, I was already experimenting with email systems, running a BBS connected to Fidonet and fetching email using UUCP.

In 1997, I wrote a webmail client in C and it ended up being used by several large companies. Inspired by that success, I went on to build a complete mail server to go with it (also in C), supporting IMAP, POP3, and SMTP.

Fast-forward a few decades, and despite the massive leaps in technology, email infrastructure still felt stuck in the past. Most mail servers were bloated, overly complex, and painful to maintain. So I decided to change that. I set out to build a modern, efficient mail and collaboration server from the ground up — this time in Rust, a language I’ve grown deeply passionate about.

That effort became Stalwart Mail & Collaboration Server — the foundation of what I now work on at Stalwart Labs.

While the C programming language will always hold a special place in my heart, I’ve embraced Rust wholeheartedly in recent years. These days, I live by the motto:

Aut Rust aut nihil 🦀 — Rust or nothing.
