不能收发外部邮件－－－ 已解决

[yohoha]

邮件服务器架在防火墙后面，外部可以访问该服务器mail.xxx.com,该服务器也可以ping通其它地址，dns解析应该是没有问题的，设置了全局网络域文档，局域网内部邮件可以收发，往外发邮件服务器就会提示Failed to connect to SMTP host xxx.com............外部往内部发邮件也进不来，郁闷死我了，到底是怎么回事呢？拜求高人指点……

看看防火墙策略,是不是防火墙把端口关闭了?

[yohoha]

防火墙打开了从邮件服务器到外部的所有端口，从邮件服务器可以ping

原来防火墙从外到内的smtp端口没有打开，现在可以收外面的邮件了，但是还是发不出去，还是说Failed to connect to SMTP host xxx.com，应该不是放火墙的问题了吧，我吧fw到外面的端口可是都打开了啊。求解……

Domino server on Windows 2000 or Windows 2003 cannot send outbound SMTP mail
Technote (FAQ)

Problem
A Domino SMTP server running on a Windows 2000 or Windows 2003 machine fails to route outbound SMTP messages, first intermittently, then completely. The server's log (LOG.NSF) may contain one or more of the following errors:

"Recipient in local Internet Domain not found, forwarding to Smart Host"
"DNS is unavailable, message will be requeued"

"DNS Resolver failed to initialize"

"Router: Unable to resolve destination domain somehost.lotus.com; DNS is unavailable, message will be requeued"

"Router: res_send failure DNS resolver error"


Cause
With the release of Windows 2000, Microsoft changed the way DNS Name Servers are recorded in the Windows Registry and the key that is used to store this information. Administrators now have the ability to specify different DNS Name Servers to use on a per network interface card level. Whereas in Windows NT 4.0, the DNS Name Server entry would be used for all network interface cards on the server. The problem reported most often is that immediately following an upgrade to Windows 2000 or Windows 2003, no mail routes outbound or to other Domino servers.

Solution
To resolve this issue, you should ensure that the "NameServer" string in the registry key indicated below is properly configured.
1. Launch the Registry (Start, Run, and type REGEDIT).
2. Look for the Registry key identified as


\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters

3. Confirm the "NameServer" string contains the correct IP address for DNS purposes; if it does not contain the correct IP address, enter it in that string.

4. If a change is made to the registry, restart the whole server to ensure the change takes effect.

大体意思是让你打开DOMINO服务器上注册表中的
\\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters
项目，然后把NameServer的值设置为你机器的首选DNS服务器IP地址，然后重启DOMINO
