Hello All,

I wrote the follownig program

Code: 
using System;
using System.Web.Mail;
public class MailHelper
{
public static void SendMail(string mailId, string author, string email,
string title, string msgDate, string comment)
{
String msg = String.Format("{0} (email: {1}) has just posted a comment
on the message \"{2}\" of your BLOG that you posted at {3}. Here's the
comment: {4}{4}{5}",
author,
email,
title,
msgDate,
Environment.NewLine,
comment
);
try
{
//SmtpMail.SmtpServer = "localhost";
MailMessage mail = new MailMessage();
mail.To = mailId;
mail.From = "[email protected]";
mail.Subject = "New BLOG comment notification";
mail.Body = msg;
SmtpMail.Send(mail);
}
catch(Exception ex)
{
Console.WriteLine(ex);
Console.WriteLine("*****************");
Console.WriteLine(ex.InnerException.Message);
Console.WriteLine("*****************");
Console.WriteLine(ex.InnerException.InnerException.Message);
throw ex;
}
}
}

The code doesn't throw any exception ... but it doesn't send the mail as
well.

I have configured the SMTP service on my local machine itself. I have
also gone into SMTP server properties and into the "Access->Relay"
option and added my machine IP (127.0.0.1 and my ip address) into the
list of "only the list below" option.

Please do help me... why am I not able to send the email?

regards,
Abhishek.

It almost sounds like your SMTP service is either not running or not
accepting calls. Try going to Outlook Express and set the SMTP server to
be localhost and try sending an email. Also, check the BadMail Folder
under mailroot directory. You might get some insight.
 
Is it the only to send an Email using CDO ?
In the past, CDO was meaning of having at least a ms-exchange client on
the pc (like outlook), and also a correct profile.

Is there another way to send an email more directly ? a SMTP Class ?

You will need outlook or outlook express to use the SMTPMail Class as it
utilizies the CDO object.

If you don't want to rely on CDO, you will need to write a class that can
connect to an SMTP server and execute the neccessary commands.
