Sending E-mails in .NET!?

Hi, guys.

I'm trying to send e-mails from my windows app, with a series of frustrations:
1) found system::net::mail.
-Got excited at first, but the problem is I need an SMTP host

2) my webhost, yahoo, does SMTP!
-problem is a) it says to use SSL and I don't know how in .NET; b) every username/password combo says Yahoo is disconnecting me, so apparently SSL is required, not optional?

3) looked for "free" smtp servers
-they all send their own message with the mail, which looks unprofessional. Also most use SSL, which I don't know how to use.

Can anyone give me a clear and simple way to get some e-mails delivered from my app, or even give me some hints where/how to start finding info on my own? Ideally, does anyone know of a tutorial? Any ideas at all (even helpful guesses) would be GREATLY appreciated. :)

Hi,

Example code for using SMTP can be found in MSDN, see
SmtpClient Class

To use SSL, check example from here:
SmtpClient.EnableSsl Property

Okay I decided to do a C# code example using GMail account, and decided to make a new post for that for clarity reasons (sorry if this is considered spamming). About the bennyboy2's question about how to use SSL, it's quite easy. SmtpClient has a property EnableSsl, which you need to set to true. GMail needs to have your username and password, and those you can set in NetworkCredential object , and pass that to SmtpClient's Credentials-property.

Below is a very simple sample that sends a test email message. It's very basic and doesn't do anything fancy, but it will get you started anyway.

Code:

---

using System;
using System.Net.Mail;
using System.Net;

namespace SmtpTest
{
  class Program
  {
    static void Main(string[] args)
    {
      Console.WriteLine("Sending test message...");
     
      // call SendTestMessage-method, with GMail server and port as parameters
      SendTestMessage("smtp.gmail.com", 587);
     
      Console.WriteLine("Message sent succesfully!");
           
      Console.ReadLine();
    }

    public static void SendTestMessage(string server, int port)
    {
      // message info
      string to = "*****.*****@gmail.com"; // put recipient
      string from = "*****.*****@gmail.com"; // put sender email here
      string subject = "SMTP client using GMail."; // message subject
      string body = "This is our test message, w00t!"; // message body
     
      MailMessage message = new MailMessage(from, to, subject, body);
     
      // Initialize client
      SmtpClient client = new SmtpClient(server, port);

      // enable SSL
      client.EnableSsl = true;
     
      // Credentials are necessary if the server requires the client
      // to authenticate before it will send e-mail on the client's behalf.     
      // Here we define our network credetials (username and password)
      NetworkCredential SmtpUserInfo = new NetworkCredential("your.username@gmail.com", "password");
     
      // set the credentials
      client.Credentials = SmtpUserInfo;

      try
      {
        // send message
        client.Send(message);
      }
      catch (SmtpException se)
      {
        Console.WriteLine("SmtpException caught in SendTestMessage(): {0}", se.ToString());
      }
      catch (Exception e)
      {
        Console.WriteLine("Exception caught in SendTestMessage(): {0}", e.ToString());
      }
    }
  }
}
