à I’m able to successfully send mail using .net code through gmail by enabling SSL.

 

But using log4net its given error:

 

My Code in app.config file:

 

     <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">

      <to value="myusername@gmail.com" />

      <from value=" myusername@gmail.com " />

      <subject value="test logging message" />

      <smtpHost value="smtp.gmail.com" />

      <authentication value = "Basic" />

      <username value = " myusername@gmail.com " />

      <password value = "mypassword" />

      <ssl value ="true"/>

      <port value ="465"/>

      <bufferSize value="512" />

      <lossy value="true" />

      <evaluator type="log4net.Core.LevelEvaluator">

        <threshold value="ALL"/>

      </evaluator>

      <layout type="log4net.Layout.PatternLayout">

        <conversionPattern value="%newline%date [%thread] %-5level %logger [%property{NDC}] - %message%newline%newline%newline" />

      </layout>

    </appender>

 

 

 

Getting error:

 

log4net:ERROR [SmtpAppender] Error occurred while sending e-mail notification.

System.Net.Mail.SmtpException: The operation has timed out.

   at System.Net.Mail.SmtpClient.Send(MailMessage message)

   at log4net.Appender.SmtpAppender.SendEmail(String messageBody)

   at log4net.Appender.SmtpAppender.SendBuffer(LoggingEvent[] events)

 

 

 

I tried using STARTTLS protocol also…which gave me an error with authentication and so….

 

 

 

Please help me out….I deadly need it work it down…

 

Best regards,

According to documentation, there is no Ssl property for SmtpAppender. According source code it is named EnableSsl, so repair your config.
But I'm not sure if it helps...

Fyi: I added the property taking reference from http://logback.qos.ch/manual/appenders.html

 

If I remove the ssl property I get the following error:

 

log4net:ERROR [SmtpAppender] Error occurred while sending e-mail notification.

System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. b39sm3288571rvf.8

do not delete ssl property, but rename it to enablessl.

strange, this property exists in source code taken from source repository. But doesn't exist in binary distribution (even there is no ssl property!), so try to get current sources from repository, compile and try again....

Works for me without any configuration exception. I had only to change port to 25, why you are trying 465? My config:

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">

<to value="raszka@hasam.cz" />

<from value="myusername@gmail.com " />

<subject value="test logging message" />

<smtpHost value="smtp.gmail.com" />

<authentication value = "Basic" />

<username value = "username" />

<password value = "mypassword" />

<enablessl value ="true"/>

<port value ="25"/>

<bufferSize value="512" />

<lossy value="false" />

<evaluator type="log4net.Core.LevelEvaluator">

<threshold value="ALL"/>

</evaluator>

<layout type="log4net.Layout.PatternLayout">

<conversionPattern value="%newline%date [%thread] %-5level %logger [%property{NDC}] - %message%newline%newline%newline" />

</layout>

</appender>

One more idea - is there any antivirus / firewall software on the computer you are doing your tests? It can block communication - I had to switch outgoing mail checking off somewhere in the past....

Try my testing project on your machine (I think lossy and buffer settings has significant effect whether message is really sent or not, but always I get no exception). If it works, search for differences in your project (notice I am using log4net build from repository, it probably will not work with release available on download page).
If not - your computer probably made god angry.

I found a change:

 

Wrt UserName & Password – what is the value we need to specify?

 

Till now I was using my gmail username & password..

 

Might be that is the mistake I’m doing…

 

Please let me know..

use username & password you are using when accesing you mail through web interface. Username should be your alias from email addres. If address is your.name@gmail.com, username should be your.name. But I don't know, if it is always true.

The issue was with the log4net.dll.. I downloaded from their site.

 

After I used the dll from ur project in my project it worked out.

 

From where I could get this valid dll..please let me know.

 

Best regards,

Sree

My suggestion would be to get email sending working using SmtpClient. There's nothing wrong with writing your own Appender. Here's one that I use for sending low volume ERROR and FATAL messages in a Medium Trust hosting environment:

    public class MediumTrustSmtpAppender : AppenderSkeleton
    {
        public string From { get; set;}
        public string To { get; set;}
        public string Subject { get; set;}
        public string Host { get; set;}

        protected override void Append(LoggingEvent loggingEvent)
        {
            MailMessage mailMessage = new MailMessage(From, To, Subject, RenderLoggingEvent(loggingEvent));
            SmtpClient smtpClient = new SmtpClient(Host);
            smtpClient.Send(mailMessage);
        }
    }
