The development of vSMTP is made possible thanks to the following projects:

  • Rust: the programming language used to develop vSMTP.
  • tokio: the asynchronous runtime and the logging framework.
  • rhai: the scripting language used in vSMTP.
  • trust-dns: the DNS resolver.
  • rustls: the TLS library.
  • serde: the serialization framework used in vSMTP.
  • rsasl: the SASL framework.

And the contributors who helped to improve vSMTP.
