Hi,

Refer the below..


Sending mail from .Net application

MailMessage mailMsg = new MailMessage();
            MailAddress mailAddress = new MailAddress("YourMailID@gmail.com");
            mailMsg.To.Add("xyz@gmail.com");
             mailMsg.CC.Add("YourMailID@gmail.com");
            mailMsg.From = mailAddress;   
            // Subject and Body          
            mailMsg.Subject = "Test mail..Please ignore";
            mailMsg.Body = "Juz i am testing whether messages are sending or not through my dotnet web application...Test mail..Please ignore";       
            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 25);
            System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("YourMailID@gmail.com", "YourPassword");  
            smtpClient.EnableSsl = true;          
            smtpClient.UseDefaultCredentials = false;         
            smtpClient.Credentials = credentials;       
            smtpClient.Send(mailMsg);

Hope this will help you

Following are the sample code for sending the email from any SMTP server.
You have to take care of port number. By default it is 25. If you want to send Gmail you have to use "587". Check for other servers.


MailMessage aMailL = new MailMessage();
                aMailL.From = new MailAddress(TxtFromEmail.Text);
                
                List<string> zEmailToListP = new List<string>() { TxtToEmail.Text };
                        foreach (string zMailAddressL in zEmailToListP)
                        {
                            aMailL.To.Add(zMailAddressL);
                        }
                
                    aMailL.Subject = "Your Subject";
                
                aMailL.Body = "Your Text";
                aMailL.IsBodyHtml = true;
                SmtpClient TheSmtpClientL = new SmtpClient();
                TheSmtpClientL.Host = zSmtpServerHostL;
                if (nPortNumberL != 0)
                {
                    TheSmtpClientL.Port = nPortNumberL;
                }
                if (bIsEnableSSL)
                {
                    TheSmtpClientL.EnableSsl = bIsEnableSSL;
                }
                if (zSmtpServerUidL != "" && zSmtpServerPwdL != "")
                {
                    TheSmtpClientL.UseDefaultCredentials = false;
                    TheSmtpClientL.Credentials = new System.Net.NetworkCredential(zSmtpServerUidL, zSmtpServerPwdL);
                }
                else
                {
                    TheSmtpClientL.UseDefaultCredentials = true;
                }
                TheSmtpClientL.Send(aMailL);

I think you will run as expected, but though the code is working well, there are still many factors that will affect mail sending functionality

1. Firewall block port 587 (This is port for smtp gmail server)
2. Internet connection is not available on machine or internet connection has face some obstacles while pinging
3. Due to some typo mistake UserName and password may be get wrong
4. Enable SSL is block email sending
5. POP settings for smtp server in your Gmail account is disabled
