Hi!

below is the smtp code i am using, i got the exceptions
'System.Web.HttpException' occurred in system.web.dll
Additional information: Could not access 'CDO.Message' object.
so in smtp virtual server properties->Access->relay selected 'all except the list below' and both above exceptions went away
but still no email was sent by the code when i checked my hotmail account
i tried using both the strings for SmtpServer = "127.0.0.1";  //"localhost"

try{
               MailMessage mail = new MailMessage();
               mail.To = "emailme@hotmail.com";
      mail.From = "emailme@hotmail.com";
      mail.Subject = "this is a test email.";
      mail.Body = "this is my test email body.";
      MailAttachment attachment = new MailAttachment( @"D:\1\trial\ProjectWorkSpace5\3769.jpg" );       mail.Attachments.Add( attachment );      
      SmtpMail.SmtpServer = "127.0.0.1";  //"localhost"
      SmtpMail.Send( mail );
      mail=null;
      attachment=null;
    }
catch(Exception ex)
   {
      MessageBox.Show("Error  :"+ex.ToString());
   }

now why would it not send the email?! ....thank you in advance for your assistance

Is a smtp server running in your localhost?  If not try giving the IP address of the smtp server...If your localhost has an smtp server running, try giving the ip address of your machine instead of the 127.0.0.1...

I think this is an SMTP server configuration problem...

Have you tried sending an email using telnet or OE to your hotmail account? Maybe DNS settings are not configured, or wrongly. Try sending a plain text message through telnet and if still no mail in your hotmail inbox, you know it is a config error

Hi:

System.Web.Mail does not give a clear picture of the failure at the first view. You may need to check out the InnerException since the Exception will always give 'Could not give CDO Message'

When you get the exception, see the InnerException and see the message it contains.

Check out: http://www.systemwebmail.com/

Alternatively, if you Interop, you can use Persits.MailSender (http://www.persits.com/)

scrac0,

do you have other service installed on the local machine, like Exchange? Also, have you checked that your SMTP server is actually running (you can check that in IIS).
If it doesn't work, go through every setting of your SMTP server. Are there IP restrictions that shouldn't be there? Check if anonymous authentication is turned on, etc.

In any case, I can tell you it is not a C# problem, but a SMTP server config error. Granted, I don't know that much about it, so if you can't get it fixed, might want to ask this in the Email / Groupware TA.

HTH,

Razzie

ps. Please respond in the question not member feedback since I don't read the latter that often :)
