나는 PHP로 작성된 스크립트를 테스트하고 있었는데, 그 스크립트가 로컬 주소로만 이메일을 보내고 있다는 것을 깨달았습니다. WebMin에 로그인하면 sendmail 대기열에 "Invalid Parameter for Delay(지연에 대한 잘못된 매개변수)" 상태의 이메일이 많이 있는 것을 볼 수 있습니다.
이메일이 어떤 도메인으로 전송되었는지에 관계없이 새로 고치려고 하면 xyz에 대한 연결이 표시되고 "지연에 대한 잘못된 매개변수"가 표시됩니다. 이는 반송된 이메일뿐만 아니라 스크립트에서 대기열에 넣은 메시지에도 동일합니다.
서버가 설정된 이후로 나가는 이메일이 없다고 가정해야 하는데, 이는 뭔가 설명이 됩니다.
이 잘못된 인수 문제를 어떻게 해결하고 sendmail이 이름에서 알 수 있는 대로 작동하도록 하려면 어떻게 해야 합니까?
고쳐 쓰다:
이 질문을 검색한 후 나는 그 어느 때보다 혼란스러워졌습니다.이것어떤 사람들은 수정자 플래그 사용을 옹호하는 것 같지만,이것삭제하라고 하더군요. 전혀 차이가 없음을 확인할 수 있습니다.
자세한 새로 고침은 다음과 같습니다.

Sendmail: 상세 모드에서 대기 중인 메시지를 강제로 전달합니다.
루트 푸시로 상세 모드에서 전체 SMTP 레코드와 함께 퀸 메시지를 보냅니다.
- mailq를 사용하여 queueid-s(메시지의 대기열 식별자)를 가져옵니다.
sendmail -v -qI...상세 모드에서 선택한 메시지를 푸시 하는 데 사용됩니다

답변2
1) bsendmail.mc의 DAEMON_OPTONS 수정자에서 플래그를 제거합니다.
b bind to interface through which mail has been received for outgoing message
오래된:
DAEMON_OPTIONS(`Name=MTA,Port=smtp,Modifiers=bh')
새로운:
DAEMON_OPTIONS(`Name=MTA,Port=smtp,Modifiers=h')
2) 수정된 sendmail.mc에서 새 sendmail.cf 파일을 생성합니다.
3) sendmail 데몬을 다시 시작/다시 로드
