Hi guys. I made a samll program to send an eamil programatically using SMTP. I don't know why, but it just gives me an error (" Faliure sending email.")

My Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net.Mail;


namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public SmtpClient client = new SmtpClient();
        public MailMessage msg = new MailMessage();

        public System.Net.NetworkCredential smtpCreds =
            new System.Net.NetworkCredential("myusername@gmail.com", "mypassword");

        public Form1()
        {
            InitializeComponent();
        }

        public void SendEmail(string sendTo, string sendFrom, string subject, string body)
        {
            try
            {
                //Setup SMTP Host Here
               
                client.Host = "smtp.gmail.com";
                client.Port = 587;
                client.UseDefaultCredentials = false;
                client.Credentials = smtpCreds;
                client.EnableSsl = true;

                //Convert strings to MailAddress
                MailAddress to = new MailAddress(sendTo);
                MailAddress from = new MailAddress(sendFrom);

                //Setup message settings
                msg.Subject = subject;
                msg.Body = body;
                msg.From = from;
                msg.To.Add(to);

                

                //Send email!
                client.Send(msg);
            }
            catch (Exception ex)
            {
                //This is just in case you type something wrong or if it cannot connect to the server
                //It will pop up with the reason why it will not work 
                MessageBox.Show(ex.Message, "ERROR");
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            SendEmail("myusername@gmail.com", "myusername@gmail.com", "Hello ", "IT WORKS!");
            
        }
    }
}

Could anyone help?

Thanks!

Are you sure gmail is 587?

Maybe helpful. I was able to connect to the SMTP server via both 465 and 587.

You might want to copy and paste the exact exception you are receiving.

"Failure sending email" is not an exception. Its a response after trying to send the email.
The only time I get this is when the server/port/username/password combo isn't right and the message can't be sent.

When I use the 587 or 25 port the message says " Failure sending message").

But when I use the 465 port the message says (" operation timed out").

I don't know why it isn't working with my computer, maybe a network problem. Do you know any other way I can send an email?

Thanks
