日志如上,发大陆邮件都正常,就发香港邮件出现这个问题,时断时续,今天早上又出现这种问题了,更改了N多个DNS还是出现相同问题.请各位高手帮我诊断诊断.

dns不稳定造成的，你更换了N多个dns，你公司有自己的dns服务器吗？这样的问题可以用中继转发解决

zjzhaojf

我们公司没有自已的DNS.中继转发具体怎么设置???

mynetway

google提供的免费DNS
8.8.8.8
8.8.4.4

zjzhaojf

8.8.8.8
8.8.4.4设了还是一样的.之前我也试用了好多个免费的DNS.

zjzhaojf

8.8.8.8 果真OK了.谢谢楼上的.不知后继还会不会出现同样的问题.

mynetway

google的DNS我用了很久，没有发生过问题。即使google的网站时打不开DNS也没试过访问不了。
不过这些DNS都是在个人电脑上用的，服务器挺稳定所以没改DNS。我用它的DNS的原因是因为它会忠实地告诉我the page cannot be displayed，而不是电信114。
无耻的电信拥有算是全球最大的用户数，却为了可怜的一点广告费做着下三滥的事。人家google，提供免费的DNS来统计用户行为、挖掘商业数据。所以IT业国内外的境界是完全不一样的，同样的资源利用方式却是天渊之别。

如果被墙了，你就换几个香港的DNS试试吧。
203.186.94.22
203.80.96.33
203.80.96.10
203.80.96.9
202.45.84.58

邮件服务器的DNS最好还是用OPEN DNS的，如Google，国内的DNS越来越差，劫持做广告却越来越厉害了。

提供一个我一直在用的香港DNS地址（有线宽频）：
61.10.0.130

我的MDaemon也是偶尔出现DNS无法解析到记录的情况,所有香港的DNS,GOOGLE8.8.8.8和8.8.4.4的DNS都试过.还是偶尔会出现,如:
Mon 2011-02-14 10:08:54: *  DNS: 20 second wait for DNS response exceeded (attempt 3 of 3)
Mon 2011-02-14 10:08:54: Attempting SMTP connection to [hessp.com:25]
Mon 2011-02-14 10:08:54: Resolving A record for [hessp.com] (DNS Server: 8.8.8.8)...
Mon 2011-02-14 10:09:14: *  DNS: 20 second wait for DNS response exceeded (attempt 1 of 3)
Mon 2011-02-14 10:09:14: Attempting SMTP connection to [hessp.com:25]
Mon 2011-02-14 10:09:14: Resolving A record for [hessp.com] (DNS Server: 8.8.4.4)...
Mon 2011-02-14 10:09:14: *  Name server has no valid records of the requested type for that domain


这个问题好烦,不知是那里的问题.??

用NSLOOKUP解析的话,又都是OK的.
