Gmail siempre convierte los correos electrónicos de dominios que terminan en .uk.net en spam, a pesar de que se aprueban SPF, DMARC y DKIM.
Si enviamos correos electrónicos desde otros dominios, por ejemplo que terminan en .co.uk, desde el mismo servidor de correo se entregan directamente a la bandeja de entrada.
Uno de los dominios .uk.net acaba de ser configurado y nunca antes había enviado correos electrónicos, el otro existe desde hace bastante tiempo.
Este NO es un correo electrónico masivo, sino simplemente correos electrónicos diarios a amigos y colegas.
¿El sistema de protección de correo electrónico de Google está mal configurado de alguna manera, por lo que los correos electrónicos de los dominios .uk.net siempre terminan en la carpeta de spam?
¿Se puede hacer algo?
