Gracias por la respuesta, pero sigo en las mismas y peor.
Hoy estuve donde dicho cliente, y presenta este error solo con los correos de una empresa, para el resto de correos externos funciona perfectamente. Ellos no manejan servidor de salida para internet, se conectan directamente al router.
Hoy hice la prueba desde mi equipo, utilizando otro ISP y el mismo error.
Este es el error que aparece:
