如何:在DotNetNuke中配置SMTP登录

有时很难对DotNetNuke应用程序中出现的SMTP问题进行故障排除。当然，您可以查看邮件服务器的SMTP日志，但这可能是配置错误，或者根本无法访问(在共享主机环境中尤其如此)。

幸运的是，有一种非常简单的方法可以为DotNetNuke生成的所有网络流量启用日志记录，其中包括SMTP流量

首先要认识到DotNetNuke电子邮件实现使用的是System.Net.Mail。除了MSDN文档关于System.Net.Mail命名空间，还有一个很好的FAQ网站:www.systemnetmail.com．

在该站点上，我们可以找到一种非常简单的方法来为邮件系统配置日志记录。实际上，这里解释的方式是，它将为应用程序完成的所有网络请求设置日志记录。这在故障排除时非常有用。

设置非常简单:

< system.diagnostics >

<消息>
<源name = "系统。网”>
<听众>
<添加name = " MyTraceFile " / >
< /听众>
> < /来源
<源name = " System.Net.Sockets " >
<听众>
<添加name = " MyTraceFile " / >
< /听众>
> < /来源
> < /来源
< sharedListeners >
<添加
name = " MyTraceFile "
type = " System.Diagnostics.TextWriterTraceListener "
initializeData = "门户/ _Default /日志/ System.Net.trace.log。资源" / >
< / sharedListeners >
<开关>
<添加name = "系统。Net" value="Verbose" />
<添加name = " System.Net。socket " value="Verbose" />
< /开关>
< / system.diagnostics >

把这个构型放在 web节点。配置后，一切都会开始工作。日志文件将创建在/Portals/_default/Logs中，也可以通过Host > Host Settings > Logs访问。

这是一个从HostSettings发送测试邮件时记录的示例:

System.Net.Sockets Error: 0: [10080] Exception in Socket#34257155::Receive -一个已建立的连接被你的主机上的软件终止。

正如您所看到的，您可以跟踪从连接到SMTP服务器的完整事件流:

System.Net.Sockets Verbose: 0: [6708] 00000000: 32 32 30 206c 6F 63 61-6C 68 6F 73 74 2073 6D:220 localhost sm
System.Net.Sockets Verbose: 0: [6708] 00000010: 74 70 34 64 65 76 20 72-65 61 64 79 0D 0A;tp4dev准备. .

这表明邮件服务器(在本例中为smtp4dev)以220状态接受连接，并准备继续。在进行了一些细微的修改(客户端向服务器授权)之后，客户端开始发送实际的消息，服务器回复说一切正常，接收方接受，然后将完整的消息(以编码文本的形式)发送到服务器。最后，消息被接受，连接被关闭:

System.Net.Sockets Verbose: 0: [6708] 00000000: 32 35 30 20 4D 61 69 6C-20 61 63 63 65 70 74 65;邮件接收
System.Net.Sockets Verbose: 0: [6708] 00000010: 64 0d0a:d . .
System.Net.Sockets Verbose: 0: [6708]退出

这是一个非常强大的选项，可以真正解决DotNetNuke和配置的SMTP服务器之间的通信问题。一个公平的警告:如果您保持此跟踪活动，它将生成一个可能非常大的文件。如果您希望在应用程序中保留这种类型的日志记录，那么确保日志文件是滚动类型可能是一个好主意。标准的TextWriterTraceListener不能做到这一点，但是创建自己的侦听器并不是很难。看看Dave Bost关于如何做到这一点的优秀博客:滚动TextWriterTraceListner日志

祝您故障排除愉快!
