// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var mailman = new CkMailMan();

// Set the SMTP server.

// Create a new email object
var email = new CkEmail();

email.Subject = "This email is encrypted";

// Emails are encrypted using the recipient's certificate.

// Indicate that the email is to be sent encrypted.
