El c\u00f3digo del proyecto est\u00e1 escrito en Rust y se distribuye bajo la licencia GPLv3.    <\/p>\n<p>De acuerdo con los resultados de las pruebas publicadas por los desarrolladores, vSMTP es diez veces m\u00e1s r\u00e1pido que los MTA competidores. Por ejemplo, vSMTP mostr\u00f3 una capacidad de procesamiento de 4 a 13 veces superior a la de Postfix 3.6.4 al transmitir mensajes de 100 KB y establecer de 4 a 16 sesiones simult\u00e1neas. Este alto rendimiento se logra gracias a la arquitectura multihilo, donde se utilizan canales as\u00edncronos para la interacci\u00f3n entre hilos.    <center><img decoding=\"async\" alt=\"vSMTP - servidor de correo con un lenguaje integrado para filtrar tr\u00e1fico \" src=\"\/wp-content\/uploads\/2022\/07\/e83c7a17a983806e63f6957e1098b1ef.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>    <\/p>\n<p>vSMTP se desarrolla con un enfoque primordial en garantizar una alta seguridad, que se logra mediante pruebas intensivas utilizando pruebas est\u00e1ticas y din\u00e1micas, as\u00ed como mediante el uso del lenguaje Rust, que permite evitar muchos errores comunes relacionados con la gesti\u00f3n de memoria cuando se utiliza correctamente. Los archivos de configuraci\u00f3n se definen en el formato TOML.      <center><img decoding=\"async\" alt=\"vSMTP - servidor de correo con un lenguaje integrado para filtrar tr\u00e1fico \" src=\"\/wp-content\/uploads\/2022\/07\/70eaf3e7acba9e6f6f0c23889a23090c.jpg\" style=\"display:block;margin: 0 auto;\" \/><\/center>        <\/p>\n<p>Una caracter\u00edstica del proyecto es la inclusi\u00f3n de un lenguaje incorporado, vSL, para la escritura de scripts de filtrado de correos, que permite crear reglas muy flexibles para filtrar contenido no deseado y gestionar el tr\u00e1fico. El lenguaje se basa en Rhai, que utiliza tipado din\u00e1mico, permitiendo la inserci\u00f3n de c\u00f3digo en programas en Rust y proporcionando una sintaxis similar a una mezcla de JavaScript y Rust. A los scripts se les proporciona una API para inspeccionar y modificar mensajes entrantes, redirigir mensajes y gestionar su entrega a hosts locales y remotos. En los scripts se admite la conexi\u00f3n a bases de datos, la ejecuci\u00f3n de comandos arbitrarios y la colocaci\u00f3n de correos en cuarentena. Adem\u00e1s de vSL, vSMTP tambi\u00e9n soporta SPF y filtros basados en listas de rel\u00e9s abiertos para combatir el correo no deseado.    <\/p>\n<p>Entre los planes para la pr\u00f3xima versi\u00f3n, se destaca la posibilidad de integraci\u00f3n con bases de datos SQL (actualmente, los datos sobre direcciones y hosts se proporcionan en formato CSV) y el soporte para mecanismos de autenticaci\u00f3n DANE (DNS-Based Authentication of Named Entities) y DMARC (Domain-based Message Authentication). En versiones m\u00e1s avanzadas, est\u00e1 previsto implementar mecanismos BIMI (Brand Indicators for Message Identification) y ARC (Authenticated Received Chain), la posibilidad de integraci\u00f3n con Redis, Memcached y LDAP, herramientas para la protecci\u00f3n contra DDoS y bots de SPAM, as\u00ed como plugins para realizar verificaciones en paquetes antivirus (ClamAV, Sophos, etc.).<br
