Re:局域网主机的主dns服务器设置问题
公司域名已经注册了,在公网上用<a target=_blank href=http://mail.xxx.cn:3000>http://mail.xxx.cn:3000</a>是可以的,内部的dns server可以解析域名和ip,但是我在www.dnsreport.com中检验了一下发现在MX的Reverse DNS entries for MX records一项是fail,出现了“ ERROR: The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site. The problem MX records are:<br>
51.135.xxx.xx.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 1)]<br>
” 是我的dns解析有问题吗? |
