DNS测试结果,版主帮忙看看

charlesdeng

我刚装了我的第一台邮件服务器(ex2003,有效域名,路由器有真实IP并做了映射),现在内部互发收发都正常,也能发往外部邮箱,但是从外部邮箱发进来就不行,退信说SMTP连接错误.已问过ISP说MX记录已经做好了.

用5Dmail的常用工具测试了一下,DNS报告中有三个黄色警告,三个红色错误.但是我洋文不行,也看不出个所以然来,只好将信息贴出来,劳烦版主和兄弟们帮忙给看看是什么问题:

Category	Status	Test Name	Information
Parent	WARN	Glue at parent nameservers	WARNING. The parent servers (I checked with d.dns.cn.) are not providing glue for all your nameservers. This means that they are supplying the NS records (host.example.com), but not supplying the A records (192.0.2.53), which can cause slightly slower connections, and may cause incompatibilities with some non-RFC-compliant programs. This is perfectly acceptable behavior per the RFCs. This will usually occur if your DNS servers are not in the same TLD as your domain (for example, a DNS server of "ns1.example.org" for the domain "example.com"). In this case, you can speed up the connections slightly by having NS records that are in the same TLD as your domain.
NS	WARN	Nameservers on separate class C's	WARNING: We cannot test to see if your nameservers are all on the same Class C (technically, /24) range, because the root servers are not sending glue. We plan to add such a test later, but today you will have to manually check to make sure that they are on separate Class C ranges. Your nameservers should be at geographically dispersed locations. You should not have all of your nameservers at the same location. RFC2182 3.1 goes into more detail about secondary nameserver location.
	WARN	Single Point of Failure	WARNING: Although you have at least 2 NS records, they may both point to the same server (one of our two tests shows them being the same, the other does not), which would result in a single point of failure. You are required to have at least 2 nameservers per RFC 1035 section 2.2.

MX	FAIL	MX is host name, not IP	ERROR: You have one or more MX record(s) that contain an IP address. This is not valid. A fully RFC-compliant mailserver will not be able to send you mail (although some mail servers will, due to the TCP/IP functions that they use). The problem MX records are: 202.158.167.14.
	FAIL	Reverse DNS entries for MX records	ERROR: None of your mail server(s) seem to have reverse DNS (PTR) entries (I didn't get any responses for them). 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 (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server).

Mail

FAIL

Connect to mail servers

ERROR: I could not complete a connection to any of your mailservers! 202.158.167.14: Could not connect without glue or A record.<br /> If this is a timeout problem, note that the DNSreport only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.

谢谢!

洋文我是看懂了,但不知道解决方案,呵

大概就是要你在建立一些你的域名信息.

我不知道你用什么工具测试.如果是内网.可以先在自己的DNS建立相关的一些记录.

我就是用5dmail网站的常用工具测试的.(链接到www.DNSreport.com)
自己的DNS已经有主机记录了,我有点怀疑是ISP的MX记录没搞妥,先不说他们技术如何,单从他们客服在电话里的表现,那种态度听着都象是敷衍,从电话里都能感觉到没拿工作当回事.
5dmail论坛的网站上既然提供了这些测试工具,相信版主应该比较熟悉的.期待版主露面指点一二?

看报告MX记录没搞定啊

charlesdeng

有没有哪位高人能把报告翻译成比较通顺的中文?
咱再来想办法解决问题.
