"La dirección IP que utilizas para enviar correos electrónicos no está autorizada..."

Gmail rechaza el correo cuando la dirección IP de envío no coincide con el dominio de envío a fin de evitar el spam. Para enviar correo desde tu servidor a Gmail, te sugerimos que utilices el relevo SMTP que te haya proporcionado el ISP. Ten en cuenta que no podemos crear una lista blanca de direcciones IP ni hacer excepciones en este momento.
