Exim4 DNS 문제

내 데비안 서버에서 평소 이메일 주소로 이메일을 전달하려고 합니다. 다음 오류 메시지를 찾기 위한 좋은 해결책을 온라인에서 찾을 수 없기 때문에 아마도 중요한 내용을 놓치고 있는 것 같습니다.

dnslookup defer (-1): host lookup did not complete

이 답변을 찾았지만 도움이 되지 않았습니다. https://serverfault.com/questions/370489/exim-cannot-send-to-remote-mail-servers

Debian-exim 사용자가 있습니다.

uid=101(Debian-exim) gid=103(Debian-exim) groups=103(Debian-exim)

내 네트워크에서 포트 25가 필터링되지 않는 것 같습니다. 어쨌든 현재로서는 DNS 문제인 것 같습니다. 여기 있는 다음 서버가 아직 작동하는지 확실하지 않으며 테스트할 다른 ​​주소를 찾을 수 없습니다.

telnet 209.85.225.27 25
Trying 209.85.225.27...
telnet: Unable to connect to remote host: Connection timed out

이것은 작동합니다:

echo "This is a test." | mail -s Testing user@localhost

다음은 수행되지 않습니다.

echo "This is a test." | mail -s Testing [email protected]
echo "This is a test." | mail -s Testing [email protected]

/var/log/exim4/mainlog에서 나는 다음을 얻습니다:

1YDDm0-0007mZ-BS <= [email protected] U=user P=local S=464
1YDDm0-0007mZ-BS == [email protected] R=dnslookup defer (-1): host lookup did not complete
1YDE1X-0007v5-EG <= [email protected] U=user P=local S=456

/etc/resolv.conf에서:

domain home
search home
nameserver 192.168.1.1

마지막으로(재미있는 부분은 마지막에 있는 것 같습니다):
