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

    // The mailman object is used for sending and receiving email.
    mailman := chilkat.NewMailMan()

    // Load the .cer file into a certificate object.
    // When sending S/MIME encrypted email, it is the recipient's
    // certificate that is used for encryption.  Only the public key
    // is needed to encrypt.  The recipient is the only
    // one possessing the private key, and therefore is the only
    // one able to decrypt.
