도메인 호스트가 아닌 기본 호스트에 의해 포착되는 이유에 대한 아이디어가 있습니까 ?
업데이트
다음은 의 출력입니다.apachectl -D DUMP_VHOSTS
VirtualHost configuration:
*:443 is a NameVirtualHost
default server mail.example.com (/etc/apache2/sites-enabled/0-default-ssl.conf:2)
port 443 namevhost mail.example.com (/etc/apache2/sites-enabled/0-default-ssl.conf:2)
port 443 namevhost example.com (/etc/apache2/sites-enabled/example.com-ssl.conf:2)
wild alias *.example.com
*:80 is a NameVirtualHost
default server mail.example.com (/etc/apache2/sites-enabled/0-default.conf:1)
port 80 namevhost mail.example.com (/etc/apache2/sites-enabled/0-default.conf:1)
port 80 namevhost example.com (/etc/apache2/sites-enabled/example.com.conf:1)
wild alias *.example.com
따라서 아마도 질문은 다음과 같습니다. 왜 mail.example.com
기본 서버 이름으로 간주됩니까? PTR이 가리키는 것이 mail.example.com
이유일까요?
