비표준 포트에서 스마트호스트를 통해 메일 보내기

GoDaddy를 통해 메일을 보내기 위해 내 sendmail 서버가 스마트 호스트 역할을 하도록 하려고 합니다. 포트 3535에서 smtpout.secureserver.net에 텔넷할 수 있고 해당 SMTP 응답이 올바른지 확인했습니다. 하지만 내 sendmail 서비스는 메일을 보낼 수 없습니다. 이유를 모르겠습니다. sendmail의 스마트호스트 부분을 다음과 같이 구성했습니다.

define(`SMART_HOST', `smtpout.secureserver.net')dnl
define(`RELAY_MAILER',`esmtp')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 3535')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash /data/smtp/client-info')dnl

답변1

sendmail은 수신측에 문제가 있을 때 어떤 단서도 남기지 않는 것 같습니다. 이전에 텔넷을 사용하여 SMTP 연결을 테스트했지만 인증이 필요하기 때문에 (텔넷을 통해) 전체 이메일을 보낼 수 없을 것 같습니다. 내가 찾은이 링크auth 명령을 빌드한 다음 이메일을 테스트하는 방법을 보여줍니다.

FROM 행에 도메인 이름에 대한 DNS 항목이 없기 때문에 수신 SMTP 서버가 메시지를 거부한 것으로 나타났습니다. 문제를 해결한 후 메일은 텔넷을 통해 전송되었고 이어서 sendmail을 통해 전송되었습니다.
