Gmail Ips address ranges
Gmail
Si, gmail tambien tiene sus lios con fallos en los SPF, con algun problema como todos. Y a diferencia del resto de los ISP, a Google como Microsoft, les tenemos tanto miedo que tenemos que protegernos de que sus ip caigan en lista negra o que incumplan lo que a nosotros se nos exige.
Esto es asi. Es imposible lidiar con un cliente, o con un administrador de una empresa que no pueda enviarnos correos porque el servidor XXX de Gmail, no ha firmado correctamente el correo con DKIM, o porque hay una falla en el SPF.
