今天忽然出现了本地用户无法通过openwebmail互相发送邮件，日志如下：
Oct 13 09:40:15 www postfix/smtpd[17373]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 554 Service unavailable; Client host [localhost] blocked using cbl.anti-spam.org.cn; from=<ruanqi88@gyee-china.com> to=<heji@gyee-china.com> proto=ESMTP helo=<gyee-china.com>
下午更换了服务器的dns后，本地用户互发邮件问题解决了，但出现了通过web方式回复邮件出现上述错误提示，新写邮件没问题得现象。
到了下午，又发现国外邮件无法发送至本地，日志如下：
Oct 13 14:05:28 www postfix/smtpd[5679]: NOQUEUE: reject: RCPT from chipog119.obsmtp.com[64.18.12.97]: 554 Service unavailable; Client host [chipog119.obsmtp.com] blocked using cbl.anti-spam.org.cn; from=<kai.liu2@ge.com> to=<jinyanxiang@gyee-china.com> proto=ESMTP helo=<chipog119.obsmtp.com>
请问这是何原因，该如何处理？
我的系统： Fedora 5 ,postfix 2.2.8-1.2

我在公司访问外网的dns 和服务器的dns 是一样的，202.106.196.115 现在也不知道怎样才能找到一个稳定的没有被劫持的地DNS 。
另外就是，现在我虽然没有在遇到上面所说的问题，但是，今天又发现 yahoo 和部分 163 的邮件被拒收，提示如下：

这两个地址在cbl.anti-spam.org.cn 都没有被列入黑名单，可为什么会被拒收呢？

我设置了dns服务器，看是外部邮件发送过来的问题解决了，现在国外和163等邮件发送都没问题了，不过又出现了下面新的问题：

我查了一下，好像是说我的反向域名解析出了问题。那么该如何查看自己的反向域名解析是否有问题呢？

反向解析从这里已经可以查得到了，我用 nslookup –qt=ptr yourIP 命令查看了一下，返回超时结果。
这可能和我在 host.conf 里面的配置有关，我设置了服务器防ping ，不知道这样是否会影响域名反向解析结果，或者说着是否会使域名反向解析失效？
#more /etc/host.conf
order hosts,bind
multi off
nospoof on

接收不到邮件说明对方解析不到您的MX记录，做过反解能解决的了吗？应该做一条备用的MX记录才行！

应该是和你的配置无关。不过你nslookup命令不对吧？应该是类似：
Quote
nslookup -qt=ptr 93.2.157.211.in-addr.arpa.
上面IP地址要反写并加上 in-addr.arpa.后缀。

反向解析看来没有问题。上次问题看来已经解决了。可是今天忽然发现有了新的问题：
服务器记录如下信息
Nov 9 13:39:35 www postfix/smtpd[2262]: warning: smtp.x263.net.cbl.anti-spam.org.cn: RBL lookup error: Host or domain name not found. Name service error for name=smtp.x263.net.cbl.anti-spam.org.cn type=A: Host not found, try again
上面这条信息是我通过foxmail用公司邮件服务器发送邮件给263的邮件后出现的。公司邮件服务器没有收到退信，263也没有收到邮件。
Nov 9 13:45:10 www postfix/smtpd[2317]: warning: 22.96.150.211.cbl.anti-spam.org.cn: RBL lookup error: Host or domain name not found. Name service error for name=22.96.150.211.cbl.anti-spam.org.cn type=A: Host not found, try again
上面这条是通过foxmail用263发邮件给公司邮件服务器后出现的,过段时间公司邮件服务器能收到该邮件。
服务器上还出现了下面的记录：
Nov 9 13:04:20 www postfix/smtpd[14764]: warning: 106.98.192.210.cbl.anti-spam.org.cn: RBL lookup error: Host or domain name not found. Name service error for name=106.98.192.210.cbl.anti-spam.org.cn type=A: Host not found, try again
ip 210.192.98.106 是我公司的固定ip，并不是公司邮件服务器的ip.
目前邮件服务器的dns是idc提供的，今天遇到问题后，分别更换为202.106.0.20 202.106.196.115 都遇到了上次提出的问题。现在比较苦恼到底有没有好用的dns了？我的邮件服务器也已经启用了dns服务功能，但似乎也没什么用处。麻烦各位高手帮帮忙。
