Debian Jessie 8.5에는 Postfix, Dovecot, Amavis, Spamassin의 메일 시스템이 있습니다.
Imap과 pop3는 잘 작동합니다. SSL을 통한 SMTP 포트 465는 잘 전송되고 배달은 잘 작동하지만 포트 25 및 587에서 "모든 로컬 수신자 및 인터넷 사서함에 대해 알 수 없는 배달되지 않은 사용자"라는 오류가 발생합니다.
내 master.cf는 다음과 같습니다.

답변1
master.cfpostfix에 다음 두 줄을 추가한 후 모든 것이 작동하기 시작했습니다.
smtp unix - - n - - smtp -v -v
smtp inet n - n - - smtpd -v -v
postfix/smtpd - 일반적으로 들어오는 메일을 처리하고 이를 적절한 내부 위치로 라우팅하는 SMTP 데몬입니다. postfix/smtp - 일반적으로 전 세계로 메일을 보내는 데 사용되는 SMTP 데몬입니다.
smtp inet n - n - - smtpd 이 줄은 postfix에게 포트 25를 통해 메일을 보내도록 지시합니다.
