2.11에서 3.4로 업그레이드한 후 Postfix Relay 액세스가 거부되었습니다.

Postfix 버전 2.11.3은 지난 몇 년 동안 완벽하게 작동해 왔습니다. 버전 3.4.14로 업그레이드한 후 서버에서 더 이상 외부로 이메일을 보낼 수 없습니다.

해당 파일에서 mail.err다음 줄을 발견했습니다.

postfix/smtpd[1043]: fatal: in parameter smtpd_relay_restrictions or smtpd_recipient_restrictions, specify at least one working instance of: reject_unauth_destination, defer_unauth_destination, reject, defer, defer_if_permit or check_relay_domains

master.cf그 후 두 매개변수를 다음과 같이 구성했습니다 .

  -o smtpd_recipient_restrictions=reject_unauth_destination
  -o smtpd_relay_restrictions=reject_unauth_destination

Postfix 버전 2.11에서는 두 매개변수가 모두 주석 처리되어 있습니다.

구성 후 메시지는 사라졌지만 파일에서 mail.err또 다른 오류를 발견했습니다 .mail.log

Jun  3 08:01:22 smtp-out postfix/smtpd[19915]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 5.7.1 <[email protected]>: Relay access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<[127.0.0.1]>

이 두 매개변수를 사용하고 있는데 sender_dependent_relayhost_maps = hash:/etc/postfix/transport_sender올바른 구성은 무엇입니까(이것이 문제인 경우)?

이것은 내 main.cf파일입니다:
