<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/nlog.xsd" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"> <targets> <target xsi:type="file"         name="default"         layout="${longdate} - ${level:uppercase=true}: ${message}${onexception:${newline}exception\: ${exception:format=tostring}}"         filename="c:\logs\default.log"         keepfileopen="false"         archivefilename="c:\logs\ntc_utility\default.{##}.log"         archivenumbering="sequence"         archiveevery="day"         maxarchivefiles="30"         /> <target xsi:type="file"     name="error"     layout="${longdate} - ${level:uppercase=true}: ${message}${onexception:${newline}exception\: ${exception:format=tostring}}"     filename="c:\logs\error.log"     keepfileopen="false"     archivefilename="c:\logs\ntc_utility\error.{##}.log"     archivenumbering="sequence"     archiveevery="day"     maxarchivefiles="90"         />  <target xsi:type="file"         name="emaillog"         layout="-------------------- ${message} (${longdate}) --------------------${newline} from: ${event-context:item=from}${newline} to: ${event-context:item=to}${newline} bcc: ${event-context:item=bcc}${newline} cc: ${event-context:item=cc}${newline} subject: ${event-context:item=subject}${newline} body: ${event-context:item=body}${newline} attachments: ${event-  context:item=attachments}${newline}--------------------------------------------------------------------${newline}"         filename="c:\logs\emaillog.log"         keepfileopen="false"         archivefilename="c:\logs\ntc_utility\emaillog_.{##}.log"         archivenumbering="sequence"         archiveevery="day"         maxarchivefiles="90"         />  </targets>  <rules> <logger name="*" writeto="error" level="error" final="true" /> <logger name="*" writeto="emaillog" level="info" final="true" /> <logger name="*" writeto="default" minlevel="debug" /> </rules> </nlog> 

this log.cs compiled utility dll

using nlog; namespace ntc.utility {     internal static class log     {         public static logger instance { get; private set;}         static log()         {             logmanager.reconfigexistingloggers();             instance = logmanager.getcurrentclasslogger();         }     } } 

this line calls logging method after email sent.

logemailsent(imperemail); 

which calls method...

    private void logemailsent(emailmessage email)     {                     logger logger = logmanager.getcurrentclasslogger();         logeventinfo thisevent = new logeventinfo(loglevel.info, "default","email sent");         thisevent.properties["from"] = email.from;         thisevent.properties["to"] = emailcollectiontocsv(email.torecipients);                     thisevent.properties["bcc"] = emailcollectiontocsv(email.bccrecipients);         thisevent.properties["cc"] = emailcollectiontocsv(email.ccrecipients);         thisevent.properties["subject"] = email.subject;         thisevent.properties["body"] = email.body;         thisevent.properties["attachments"] = attachmentcollectiontocsv(email.attachments);         logger.log(thisevent);      } 

check nlog.config if not. there posibilities configurations injected within code..
