EmailEncoder uses log4net 1.2.10 and is configured using the normal log4net configuration file.
In EPiServer solutions this is the EPiServerlog.config file
If you want to capture logging for EmailEncoder to a separate file, add the following segment to your log4net configuration file.
Snippet
<appender name="EmailEncoderAppender" type="log4net.Appender.RollingFileAppender" > <file value="App_Data/emailencoderLog.txt" /> <rollingStyle value="Date" /> <datePattern value="yyyyMMdd" /> <maxSizeRollBackups value="10" /> <staticLogFileName value="true"/> <encoding value="utf-8" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <appendToFile value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date %level [%thread][%logger] %type.%method - %message%n" /> </layout> </appender> <logger name="EmailEncoder"> <level value="All" /> <appender-ref ref="EmailEncoderAppender"/> </logger>
Change the location of the logfile if needed and if the logging gets to verbose, change the level to Error.
