Drupal을 통해 보낸 이메일을 릴레이하기 위해 SendGrid를 사용하고 있습니다. DKIM, DMARC, SPF, 역방향 DNS 등 모든 것을 사용함에도 불구하고 Gmail에서 가입 확인 이메일을 스팸으로 표시하는 데 어려움을 겪고 있습니다. SendGrid를 2개의 전용 IP를 사용하도록 설정했습니다.
동일한 CMS를 통해 전송된 다른 거래 이메일에서는 이런 일이 많이 발생하지 않습니다(또는 적어도 사용자로부터 많은 보고서를 받지 못했습니다). 그래서 이메일 사본에 관한 것인지 궁금합니다(아마도 제목에 이메일과 비밀번호라는 단어를 사용했을까요?).
이메일은 다음과 같습니다.

편집하다:또 다른 테스트를 수행한 후 DMARC가 실패한 것으로 보이는 인스턴스를 발견했습니다.https://www.mail-tester.com/test-tri7i0dx9&reloaded=1
그 이유는 이메일이 DMARC를 통과한 이메일과 정확히 동일한 IP 주소에서 전송되었기 때문에 무엇이 잘못되었는지 이해하는 데 어려움을 겪고 있기 때문인지 잘 모르겠습니다.
스팸으로 표시되는 이유에 대해 어떻게 생각하시나요?
답변1
모든 이메일 서비스 제공업체에는 스팸 탐지를 위한 고유한 비밀 방법이 있습니다. SPF, DKIM 및 DMARC는 이에 대한 역할을 하지만 이메일의 출처만 확인합니다. 다음과 같은 2가지 이유로 인해 어떤 제공자도 자신의 규칙이 어떻게 작동하는지 정확히 알려주지 않습니다.
- 스패머가 규칙을 우회하는 것이 더 쉬워집니다.
- 공급자는 일부 필터가 어떻게 작동하는지 모르는 경우가 많습니다.
그러니 아무도 당신의 질문에 대답할 수 없습니다.
귀하는 올바른 일을 하고 있습니다(귀하의 RMX가 약간 까다롭기는 하지만 - OTOH - Sendgrid + Sendgrid의 호스팅에 의해 제어되기 때문에 이를 변경할 수 없습니다. / RMX는 일부 공급자가 여전히 사용하고 있음에도 불구하고 더 이상 사용되지 않습니다).
