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.
