sjXXXX@eastpost.co.kr  <- 이쪽으로 메일을 보내려고  메일이 보내지지 않고 참조로 같이 보낸 mXXX@unitel.co.kr

메일로는 메일이 간것으로 보이는데요...그리고는...리턴메일로

보낸이에게 메일이 온것같구요...;;;;

또 외국 업체로도 메이이 가지 않는 현상도 있습니다.

에효...리눅스 너무 초보다 보니...로그를 봐도 헤깔리고 잘 모르겠네요

ㅠㅠ 도움 좀 부탁 드립니다~

 

그리고 RBL 외국 사이트에 자꾸 블록이 걸려서 해제는 계속 시키고 있

는데요 괜찮다가고 몇일뒤에 또 걸리고 그래서 접속 할때마다

리버스 DNS 설정이 안되어있다 해서 .rev 파일을 만들어서 PRT 등록을

을 하고 reverse DNS를 서정했는데요 해당 사이트에서 검색 해보면

여전이 reverse DNS 이 안된다고 나오는데 이건 왜그럴까요 ㅠㅠ;;

서버 자체내에서 nslookup 을 해보면....리버스 잘뜨는데 말이죠..ㅠㅠ
