Send email using System.Net.Mail
To send mail using System.Net.Mail, you need to configure your SMTP service in your application's web.config file using these values for mailSettings:
<system.net>
<mailSettings>
<smtp from="your email address">
<network host="relay-hosting.secureserver.net" port="25" />
</smtp>
</mailSettings>
</system.net>
The network rule's value will be used when you instantiate an SmtpClient in your code.
C# code example
You can then use code similar to this to send email from your application:
MailMessage message = new MailMessage();
message.From = new MailAddress("your email address");
message.To.Add(new MailAddress("your recipient"));
message.Subject = "your subject";
message.Body = "content of your email";
SmtpClient client = new SmtpClient();
client.Send(message);
message.From = new MailAddress("your email address");
message.To.Add(new MailAddress("your recipient"));
message.Subject = "your subject";
message.Body = "content of your email";
SmtpClient client = new SmtpClient();
client.Send(message);
