He estado luchando para descubrir por qué ocurre esto, pero mis correos electrónicos están siendo marcados como spam por Gmail y Hotmail (funcionan en Yahoo).Correos electrónicos marcados como spam: pases SPF, pases DKIM, pases de id. De remitente
SPF, DKIM, rDNS y sender-id todos pasan. Lo que es más extraño es que he enviado el mismo correo electrónico EXACTO con sus contenidos exactos de mi servidor de desarrollo y Gmail lo acepta como no spam a pesar de que todos los controles que pasan en producción fallan en el desarrollo. Sin embargo, Hotmail todavía lo marca como spam.
¿Alguna idea de lo que podría estar pasando? He aquí un ejemplo de cabecera de Gmail (con direcciones IP y dominios cambiado por privacidad):
