Introducción
Este documento describe cómo probar el correo y la conectividad de red a través de un dispositivo de seguridad del correo electrónico (ESA) con smtpping.
¿Cómo pruebo el correo y la conectividad de red con un ESA usando smtpping?
En su Cisco ESA, para resolver problemas correctamente los problemas de red e identificar los errores de transmisión, usted puede desear ver la validación de los mensajes de error vistos dentro de los registros del correo al enviar a un MTA determinado.
Para utilizar las herramientas de diagnóstico tales como smtpping, usted necesita conectar con el CLI de su ESA.
Usted puede entonces ejecutar el diagnóstico > la red > smtpping.
Siga las instrucciones de probar la Conectividad o de enviar un mensaje de prueba.
