Download: Chilkat .NET Assemblies

This is a simple example demonstrating how to send mail via an SMTP server in C#.

		private void SendMail_Click(object sender, System.EventArgs e)
		{
			// Create a mailman object for sending email.
			Chilkat.MailMan mailman = new Chilkat.MailMan();

			// Anything begins the 30-day trial.
			mailman.UnlockComponent("30-day trial");

			mailman.SmtpHost = "smtp.earthlink.net";
			// The SMTP username and password are only necessary if
			// your SMTP server requires authentication.
			mailman.SmtpUsername = "myLogin";
			mailman.SmtpPassword = "myPassword";

			// Create an email object
			Chilkat.Email email = new Chilkat.Email();
			email.Subject = "This is the subject";
			email.Body = "This is the body";
			email.AddTo("John Smith","john.smith@chilkatsoft.com");
			email.From = "Chilkat Software <support@chilkatsoft.com>";

			bool success = mailman.SendEmail(email);
			if (!success) 
			{
				MessageBox.Show(mailman.LastErrorText);
				mailman.SaveLastError("sendError.xml");
			}
			else
			{
				MessageBox.Show("Message Sent!");
			}
