Para reenviar el correo electrónico de validación de su solicitud ACM de certificado

El siguiente comando resend-validation-email indica a la autoridad de certificación de Amazon que envíe un correo electrónico de validación a las direcciones correspondientes:

aws acm resend-validation-email --certificate-arn arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012 --domain www.example.com --validation-domain example.com

Ejemplo 1: Solicita que se envíe el correo electrónico para validar la propiedad del dominio de «www.example.com». Si el valor $ del shell ConfirmPreference está configurado en «Medio» o en un valor inferior, el cmdlet solicitará una confirmación antes de continuar. Añada el modificador -Force para suprimir las solicitudes de confirmación.
