POSTFIX: 보낸 사람 주소 거부됨: 도메인을 찾을 수 없음(MAIL FROM 명령에 대한 응답)

내 메일 서버가 $mydestination을 인식하지 못합니다. 이유는 무엇입니까?

답변1

원격 메일 서버에서 받은 오류 메시지는 다음과 같습니다.

호스트 smtp.terra.com.br[208.84.244.140] 말했다: 450 4.1.8 : 보낸 사람 주소 거부됨: 도메인을 찾을 수 없음(MAIL FROM 명령에 대한 응답)

이는 다음을 의미합니다.에서해당 도메인에 대한 DNS 조회가 실패했기 때문에 주소가 거부되었습니다.

문제의 도메인은 sales.intra내가 찾을 수 있는 어떤 DNS 서버에서도 확인되지 않는 것 같습니다.

이 작업을 수행하려면 공용 DNS에서 확인을 수행 sales.intra하거나 FROM 주소를 확인 가능한 주소로 변경해야 합니다.

제대로 작동한 이메일은 원격 서버가 아닌 로컬로 전달되었습니다. 로컬 서버는 FROM 주소에서 유효한 작동 도메인을 확인하지 않으므로 이메일 처리를 계속합니다.
