sendmail을 처음 사용하는 초보자입니다. 문제 메일만 도착하지 않습니다(스팸도 아님). 다음 로그가 있습니다.

메일.오류비었다

메일.로그표시 accepted for delivery되지만 언젠가는 발생 stat=Deferred: Connection timed out with alt4.gmail-smtp-in.l.google.com하지만 항상 그런 것은 아니므로 이것이 문제가 될 수 있는지 확실하지 않습니까?

이미 포트 25가 열려 있는지 확인했습니다.netstat -tuplen | grep 25

답변1

나가는 smtp 연결이 ISP에 의해 차단될 수 있습니다(발신 스팸 방지).

gmail.com MX의 SMTP 포트를 텔넷으로 연결할 때 SMTP 인사말 메시지를 받나요?호스트로부터? [sendmail의 잘못인가요?]

Gmail MX 목록을 얻으려면 다음을 사용하십시오.dig MX gmail.com

SMTP 인사말 사용을 가져오거나 확인하려면:telnet gmail-smtp-in.l.google.com 25

귀하의 출력에 따르면 netstat -ntlp | grep sendmail귀하의 서버는 귀하의 IP 주소가 아닌 localhost(127.0.0.1)에서만 수신 대기하고 있습니다. 이메일을 받고 싶다면 확인하세요.이것.

확인하다:

  • DNS: host -t mx gmail.com. 대답은 다음과 같습니다.

    gmail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 5 gmail-smtp-in.l.google.com.
gmail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com.

  • 추가 DNS: host alt4.gmail-smtp-in.l.google.com(또는 다른 Gmail SMTP 서버). 대답은 다음과 같습니다.

    alt4.gmail-smtp-in.l.google.com has address 209.85.202.27
alt4.gmail-smtp-in.l.google.com has IPv6 address 2a00:1450:400b:c00::1a

  • SMTP 포트 액세스: nc -vv alt4.gmail-smtp-in.l.google.com 25220 코드를 받아야 합니다.

    220 mx.google.com ESMTP 7si2060923qty.86 - gsmtp [831 ms]

그렇지 않은 경우 ISP가 포트 25를 차단하고 있을 수 있으며 SSL을 통한 SMTP(포트 465) 또는 SMTP 제출(포트 587)을 사용해 볼 수 있습니다.
