Estoy usando SendGrid para transmitir correos electrónicos enviados a través de Drupal. Estoy luchando con Gmail para marcar específicamente los correos electrónicos de verificación de registro como spam a pesar de usar DKIM, DMARC, SPF, DNS inverso, todo lo que hay... He configurado SendGrid para usar 2 IP dedicadas.
Esto no sucede tanto con otros correos electrónicos transaccionales enviados a través del mismo CMS (o al menos yo no he recibido tantos informes de usuarios). Entonces me pregunto si se trata de la copia del correo electrónico (¿quizás usando las palabras correo electrónico y contraseña en el asunto?).
Aquí está el correo electrónico:

EDITAR:Después de hacer otra prueba, detecté un caso en el que aparentemente DMARC falló:https://www.mail-tester.com/test-tri7i0dx9&reloaded=1
No estoy seguro de por qué, porque el correo electrónico proviene exactamente de la misma dirección IP del correo electrónico que pasó por DMARC, por lo que me cuesta entender qué está mal.
¿Alguna idea sobre por qué se marcan como spam?
Respuesta1
Cualquier proveedor de servicios de correo electrónico tiene su propia receta secreta para detectar spam: SPF, DKIM y DMARC desempeñan un papel en esto, pero solo VALIDAN EL ORIGEN del correo electrónico. Ninguno de los proveedores le dirá exactamente cómo funcionan sus reglas por 2 razones:
- hace que sea más fácil para los spammers eludir las reglas
- Los proveedores a menudo no saben cómo funcionan algunos de sus filtros.
Entonces nadie puede responder a tu pregunta.
Estás haciendo lo correcto (aunque tu RMX es un poco tonto - OTOH - no puedes cambiar esto ya que está controlado por Sendgrid + el alojamiento de Sendgrid / RMX está en desuso a pesar de que algunos proveedores todavía lo usan).
Lo único que noto aquí es quepodríaayudar al DPI es agregar unencabezado para cancelar la suscripción.
