C# source code showing how to send a high-priority mail.

	bool success;

	// Create a mailman object for sending email.
	Chilkat.MailMan mailman = new Chilkat.MailMan();

	// Any string argument automatically begins the 30-day trial.
	mailman.UnlockComponent("30-day trial");

	// Set the SMTP server.
	mailman.SmtpHost = "smtp.earthlink.net";

	// Create a high-priority email.
	Chilkat.Email email = new Chilkat.Email();

	// Set the basic email stuff: body, subject, "from", "to"
	email.Body = "This is the email body";
	email.Subject = "This is the email subject";
	email.AddTo("Chilkat Support","support@chilkatsoft.com");
	email.From = "Programmer <programmer@chilkatsoft.com>";

	//You can add the X-Priority header field and give it the value string "1". 
	//For example: email.AddHeaderField "X-Priority","1" This is the most common way of 
	// setting the priority of an email. "3" is normal, and "5" is the lowest. 
	// "2" and "4" are in-betweens, and frankly I've never seen anything 
	// but "1" or "3" used. Microsoft Outlook adds these header fields when 
	// setting a message to High priority: 

	// X-Priority: 1 (Highest) 
	// X-MSMail-Priority: High 
	// Importance: High 

	// This field alone is enough to make the email high-priority.
	email.AddHeaderField("X-Priority","1");

	success = mailman.SendEmail(email);
	if (success)
	{
		MessageBox.Show("Sent high-priority email!");
	}
	else
	{
		MessageBox.Show(mailman.LastErrorText);
	}
