Top 12 Rust SMTP Projects

  • check-if-email-exists

    Check if an email address exists without sending any email, written in Rust. Comes with a ⚙️ HTTP backend.

    • Project mention: Looking for help in GPL project | /r/rust | 2023-05-31

    The point is not about ideological debates, making money from GPL software is purely a practical business decision. Many people are doing it, see e.g. https://reacher.email/ (written in Rust btw).

  • mail-server

    Secure & Modern All-in-One Mail Server (IMAP, JMAP, SMTP)

    • Project mention: Happy 20th Anniversary, Gmail. I'm Sorry I'm Leaving You | news.ycombinator.com | 2024-04-15

    * [1] should be https://stalw.art

    It's a neat project though, that I hadn't heard of before. I have ran Postfix to do domain-wide email forwarding (to Gmail coincidentally) but going the other way around and having the end destination be self hosted is on my to-do list.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
