（求助）用MDaemon架设邮件系统，只能收信，不能发信，Help！

ekaiser

近日给一家公司做网络系统，采用的是2MADSL上网方式，于是内部组成局域网，通过ADSL MODEM的路由功能共享上网。并购买了旭锐达公司（http://www.sharella.com）的动 ... �电脑上架设web ftp mail，但是在架设mail服务器的时候，发现有些问题，主要问题为内网架设的mail服务器不能往外发送邮件，虽然邮件系统提示已发送，但是过了许久会收到系统的一封退信，表明发送并未成功。我用MDaemon7.00架设邮件服务器。系统用windows2000Server版。
通过查看出错原因，邮件系统这样显示：

以上两种情况出现在各大门户邮件地址中。

但是也有一个邮箱是例外的，就是浙江互联星空提供的邮件系统——zjip.com却发送成功！

出现这样的问题我查了很多原因，从服务器系统（换了2000server到2003）到邮件系统（MDaemon的各中英文版本），均出现同样的问题。我想请问这是什么原因？是动态服务内网系统造成的吗？我给很多单位都架设过邮件系统（有固定公网IP和动态域名非内网），都没出现这样的问题！特请技术员帮助解决，否则我的邮件系统只能收邮件，不能发邮件，功能是残缺的，达不到预期的效果！切以回复解决为盼，谢谢！

看Winsock错误提示是对方邮件服务器要么是Down了，要么是拒绝你连接这个IP或者是这个端口，出这个错误，有可能是对方邮件服务器的问题，和你的邮件服务器没有关系。

Sat 2004-07-03 09:16:24: A-record resolution of [citiz.net] in progress (DNS Server: 10.0.0.138)...
Sat 2004-07-03 09:16:25: Name server has no records of the requested type for that domain.

这个错误提示说NameServer就没有这个citiz.net的记录，说明这个邮件地址就有问题。你PING一下citiz.net根本就不通，PING这个www.citiz.net才是通的，所以，[email protected]这个邮件地址就是有问题的。邮件服务器的MX记录就没有查询到。


最后发送成功的这个邮件地址所在的服务器是正常的，邮件服务器的NameServer记录也是存在的，即对方邮件服务器的MX记录可以查询到。


所以不一定就是你这个邮件服务器有问题，不可能你发送的所有邮件都会有问题吧？换别的邮件地址发送试试看，不行就用我的。

citiz.net是上海吸铁石邮局
我今天分别用[email protected]向 163.com 126.com 263.net tom.com sina100.com hotmail.com yahoo.com.cn 发送邮件，均未获成功！只有zjip.com这个成功收到信件。这里肯定有原因的啊 ，难道是内网惹的祸？我的服务器架设在内网，用的是内网IP，域名用了动态主机服务（内网）的。

ekaiser

我估计是 “要么是拒绝你连接这个IP或者是这个端口”这个原因居多，因为从日志上看也多是这种情况，那么出现这种情况，该如何解决呢？请指教！

笑傲江湖

那我估计就是DNS的问题了，Mdaemon可以指定DNS的我记得，试试看把DNS设置好。因为从你的日志中显示是这个：DNS Server: 10.0.0.138

ekaiser

我是开通阿尔卡特的511e 猫上的路由的 10.0.0.138是进入猫的ip。

cummingte

10.0.0.138是网关而不是DNS服务器！
你在Mdeamon中手动指定DNS服务器了？让他自己找吧，要不然就用那个202.101.172.51或者是202.101.172.37

ekaiser

没有手动指定服务器 安装软件的时候那个选项是留空的

看来问题也不是出在这里   各位还有何高见？

端口映射的问题，你的ADSL猫开启了路由功能，那么就设置一个所有端口都映射到服务器的IP上吧
