log4net smtp appender not sending emails

Question

I'm trying to implement log4net to send email.
The following is my code but it's not sending emails.

 <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
  <to value="...." />
  <from value="..." />
  <subject value="Logging Message" />
  <smtpHost value="smtp.gmail.com" />
  <port value="465"/>
  <authentication value="Basic" />
  <username value="..."/>
  <password value="..."/>
  <EnableSsl value="true" />
  <bufferSize value="1" />
  <lossy value="true" />
  <evaluator type="log4net.Core.LevelEvaluator">
    <threshold value="WARN"/>
  </evaluator>
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %level %logger - %message%newline%exception" />
  </layout>
</appender>

and

<root>
  <level value="WARN" />
  <appender-ref ref="SmtpAppender" />
</root>

in the AssemblyInfo.cs

 [assembly: log4net.Config.XmlConfiguratorAttribute(Watch = true)]

and that's how I create the log object

  private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

This configuration is working fine for file output i.e. RollingFileAppender but not for SmtpAppender.

N i have tried many solutions from the internet but were not really helpful.

Please show me the right directions. thankx in advance :)

Answer 1

I'm using a very similar appender for SMTP messages to Gmail, but in my case I use a different port:

<port value="587"/>

All the other settings are the same, so give that a try and see if it works for you. It's the port Gmail uses for TLS, referenced here.
