Tengo un problema, de vez en cuando me llegan correos duplicados de un servidor. Pense en principio que se trataba de que el servidor de origen estaa mal configurado o algo asi. Pero hoy DIA DE LA MUJEr, se me ocurrio enviar una postal de gusanito a mis compañeras de trabajo y no paro de recibir las tarjetas. Asi que quizas el problema de la duplicación de correo este en mi servidor.

Tengo Sendmail corriendo en uun redhat 8.0, Ip privada con FWD desde una IP publica que me hace de firewall.

Los dominios son falsos, por razones de seguridad
servidorcorreo.com.ec es mi Dominio
gracias
