Diagnostics: How to enable debug tracing for System.Net.Mail API?
You can enable the following trace switches in your application config file, so that you can enable tracing for The System.Net.Mail library/API. This will log the contents of the SMTP session to a file. To send traces to a log file, add the following node to the <system.diagnostics>
node of the appropriate configuration file (application or machine). You can change the name of the file (trace.log) to suit your needs, like what i did below as “System.Net.trace.log”.
So the below example will log the SMTP session in a file, "System.Net.trace.log". You can have a look it, which will be helpful for your detailed debugging/troubleshooting purpose.
<configuration>
<system.diagnostics> <trace autoflush="true" />
<sources>
<source name="System.Net" >
<listeners>
<add name="MyTraceFile"/>
</listeners>
</source>
<source name="System.Net.Sockets">
<listeners>
<add name="MyTraceFile"/>
</listeners>
</source>
</sources>
<sharedListeners>
<add name="MyTraceFile" type="System.Diagnostics.TextWriterTraceListener" initializeData="System.Net.trace.log" />
</sharedListeners>
<switches>
<add name="System.Net" value="Verbose" />
<add name="System.Net.Sockets" value="Verbose" />
</switches>
</configuration>
Hope this helps.
