마지막 날 나는 이 문제에 대한 해결책을 찾고 있었습니다.
내 postfix(+dovecot) 구성은 전자 메일을 완전히 수신하고 IMAP을 통해 이를 제공할 수 있지만 SMTP(포트 587)를 통해 전자 메일을 수락하는 데는 실패합니다.
나는 이미 추가를 시도했습니다example.net에게릴레이_도메인, 그러나 이미 가상 사서함 도메인 데이터베이스에 있으므로 실패했습니다.
이미 추가하려고 했는데mail.example.net가상 사서함 도메인 데이터베이스에.
설정을 위해 나는 따랐다아르스테크니카'에스가이드이메일 서버 설정에 대해 아마도 몇 가지 요소를 인식하게 될 것입니다. 참고: postfix-dovecot 번들이 부족해서 가이드를 정확히 따라갈 수 없었는데 메일을 받을 수 있어서 잠재적인 문제를 극복한 것 같습니다.
추가 참고 사항: 다른 주소로 보내기(예:[이메일 보호됨]) 작동합니다.
필요한 모든 파일을 제공할 수 있습니다.
필요한 경우: postfix 버전 2.11.3
참고: example.net은 내 도메인을 대체합니다. 유효하고 DNS가 설정되었으며 유효한 TLS 인증서가 설치되었습니다.

답변1
거부의 원인은 입니다 smtpd_recipient_restrictions. 삭제 reject_unauth_destination하면 smtpd_recipient_restrictions문제가 해결됩니다.
는 이미 넣었 reject_unauth_destination으니 smtpd_relay_restrictions다시 넣을 필요는 없습니다 smtpd_recipient_restrictions.
답변2
이것은 로그에서 알 수 없는 부분입니다. 마세갈로에의 답변으로 이어집니다.
