Postfix를 사용하여 SMTP로 이메일을 보내려는 고객이 있습니다. postfix는 이메일 속성을 올바르게 구문 분석하는 것으로 보이지만 이메일을 보내기 전에 다시 처리를 시작합니다. 이것은 무한 루프에서 발생합니다. 나는 postfix를 디버그 모드로 설정하고 이메일 구문 분석을 반복하는 지점까지 내 시스템에서 생성된 로그 파일과 거의 똑같아 보이는 로그 파일을 생성했습니다.
고객의 로그 끝:
postfix/smtpd[29586]: connection closed
postfix/smtpd[29586]: connection established
내 로그 끝:

대기열 로그에는 거부된 이메일에 대한 정보가 없습니다. 실행해도 mailq > mailqueue.txt의미 있는 정보가 생성되지 않았습니다. 또한 고객에게 postqueue -fpostfix를 사용하여 대기열을 플러시하고 다시 시작하도록 요청했지만 아무 도움도 되지 않았습니다.
postfix가 이메일을 보내는 대신 구문 분석을 반복하게 만드는 원인은 무엇입니까?

답변1
authnz.prod-c15a-awsuse.proofpoint.com[205.220.189.150] 말했다: 530 5.7.0 인증 필요(MAIL FROM 명령에 대한 응답)
구성한 릴레이를 인증하지 않은 것 같습니다.
relayhost = authnz.proofpoint.com:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_password
의 내용을 확인하세요 /etc/postfix/smtp_password. 구체적으로,접미사는 다음을 지시합니다.Relayhost 값과 맵 조회 키 사이의 형식을 일치시킵니다.
Relayhost 대상에 기본이 아닌 TCP 포트(예: ":submission" 또는 ":587")를 지정하는 경우 smtp_sasl_password_maps 파일에서 동일한 형식을 사용해야 합니다.
이것이 실제로 해당 비밀번호 맵에 문제가 있는 것으로 판명되면 발행하여 색인화된 캐시를 업데이트하는 것을 잊지 마십시오 postmap /etc/postfix/smtp_password. 대기열에서 아직 배달되지 않은 메시지에 어떤 일이 발생해야 하는지 고려하십시오.5월배달 못 함 알림을 전달하는 것(아마도 많음) 이외의 다른 경로를 통해 영향을 받는 받는 사람과 보낸 사람을 업데이트하려고 합니다.
