exim4 에서 메일이 제대로 전송되지 않는 경우
글쓴이: 권순선 / 작성시간: 일, 2005/08/07 - 5:26오후
http://kldp.net 에서 exim4를 mta로 사용하고 있고, /etc/aliases 에 webmaster가 alias로 다음과 같이 지정되어 있는데 이 주소로 메일이 제대로 전송되지 않습니다.
webmaster: root root: kss kss: 제 실제 이메일 주소
kldp.net에서 exim4 -d -bt webmaster@kldp.net 을 실행해본 결과는 다음과 같습니다.

우선 저는 exim에 대해 전혀 아는 바가 없다는 것을 밝힙니다.
설치조차 해본 적이 없습니다. :oops:
그냥 답변이 없길래, 로그만 보고 추측성 글을 올립니다.
system alias의 내용중
webmaster: root윗 부분이 적용되는 것이 의도하신 것과 다른 것 같습니다.
즉, webmaster@kldp.net 이 root@kldp.net 으로 의도하신것 같은데
root@mail.kldp.net 으로 변환되네요.
호스트네임이 mail.kldp.net이고 exim의 alias 해석기가 아마도 호스트네임을 갖다붙이는 식으로
동작하는 것이 아닐까 싶습니다.
그리고 exim이 설치된 시스템이 210.118.94.78인데 이 시스템의 exim은
mail.kldp.net으로 배달되어 오는 메일을 로컬메일로 처리하지 않도록 설정되어 있군요.
결국 종합해보면 첫단계 alias가 해석되어 root@mail.kldp.net으로 메일을 전달해야하는데,
이 시스템은 mail.kldp.net에 대한 메일을 처리하지 않도록 설정되어 있어서
remote호스트라 생각하는데, dns resolve 결과는 local ip가 떨어지니까
exim이 전달을 포기해 버리는 상황 같습니다.
alias가 root@kldp.net으로 해석되도록 하는 방법과
exim이 mail.kldp.net을 로컬메일로 인식하도록 하는 방법중
한가지만 적용하셔도 문제는 해결될 것 같습니다.
하지만 통상적인 사용에 비추어볼때, 둘다 적용하시는게 의도하시는 내용이 아닐까 추측되네요.
[quote="yoocj9"]우선 저는 exim에 대해 전혀 아는 바가
아 그렇군요! 호스트네임은 다른 것으로 되어 있는데... 일단은 간단하게 /etc/aliases를 수정해서 root을 root@kldp.net으로 고쳤습니다.
감사드립니다....
