Conoce nuestro método patentado

1. Obtenemos parte de la evidencia justo antes de entregar el email 

Lo primero que hacemos es obtener la información relevante contenida en la cabecera del email. A continuación, utilizamos criptografía estándar para calcular un hash del email original; si el email incluye adjuntos, también obtenemos hashes adicionales de cada archivo.

Los datos de cabecera y cada hash quedan vinculados a un ID de registro único y registrados para su uso futuro. Este registro está disponible un segundo después de que nos llegue tu email, de forma que puedas consultar su estado en tiempo real desde el panel de usuario o por medio de nuestros web services.

2. Entregamos tu correo como lo haría cualquier proveedor de servicios de email

Cuando entregamos un email en tu nombre, no hacemos nada que no harían otros servidores de correo. Conectamos con el servidor de correo del destinatario resolviendo su dirección MX, entregamos el email mediante una conexión SMTP convencional y registramos el detalle de la transmisión. Esto incluye la confirmación de aceptación proporcionada por el servidor de correo del destinatario. Cuando el email va digirido a dos o más destinatarios, repetimos el mismo proceso para cada uno de ellos.

Para los emails que envías tú: el destinatario lo recibe como un email corriente sin referencia alguna al proceso de certificación. No se requiere ninguna acción por su parte para que el proceso tenga éxito y podamos emitir la evidencia que necesitas.

Para los emails que te envían a ti: el remitente simplemente se limita a enviar su email a la dirección que tu les proporcionas. El hecho de que el email pase a través nuestro no es realmente asunto suyo. Esto lo tratamos contigo.

3. Completamos la evidencia y la ponemos a tu disposición

Emitimos un certificado en formato PDF que contiene la información habitual de cabecera de un email, los nombres y hashes de todos los archivos relacionados, datos clave de su transmisión al servidor de correo de cada destinatario y una versión impresa de las cabeceras y del cuerpo del mensaje.

Para mayor claridad y solidez de la evidencia, incluimos una copia completa del email original en formato EML estándar con sus archivos adjuntos también

Una vez completado, el certificado de evidencia se firma electrónicamente para garantizar su integridad y queda inmediatamente puesto a tu disposición, ya sea mediante un email a tu buzón, accediendo a la consola de usuario de eEvidence o en tus propios sistemas via API.
