Gmail 및 Hotmail에서 Postfix 메일이 스팸으로 분류됨(모든 방법을 시도했지만 여전히 문제가 해결되지 않음)

Gmail 및 Hotmail에서 Postfix 메일이 스팸으로 분류됨(모든 방법을 시도했지만 여전히 문제가 해결되지 않음)

누군가 도와주세요. 중복되지 않습니다. 웹 전체에서 찾을 수 있는 모든 답변을 살펴보고 다양한 방법을 시도했지만 여전히 스팸 폴더에 들어가지 않도록 할 수 없습니다.

Let's Encrypt SSL, DKIM 유효, SPF 통과 및 DMARC 통과를 통해 postfix, dovecot, mysql, spamassassin을 실행하면 PTR 레코드가 설정됩니다. 도움이 될 수도 있다고 생각하는 ClamAV 및 Amavis도 구성했지만 여전히 스팸 폴더로 이동합니다.

호스트 이름은 mail.devexus.net입니다.

/etc/hosts 파일

127.0.0.1       localhost.localdomain locahost
127.0.0.1       mail.devexus.net mail.devexus.net

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

스팸으로 분류된 메일의 헤더는 다음과 같습니다.

IP를 확인해 보니 어디에도 블랙리스트에 등록되어 있지 않습니다.

그렇다면 여전히 문제가 될 수 있는 것은 무엇입니까?

"Received From"과 호스트 및 호스트 이름에 문제가 있는 것일까요?

"mail.devexus.net"이 문제인가요? 메일을 삭제해야 할까요? devexus.net으로만 나가시겠어요?

이것은 linode에서 호스팅되고 있습니다. 문제가 될 수 있습니까?

정말 미칠 것 같아요. 이 문제를 해결하는 데 2~3일이 걸렸습니다.
