* 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.
loMailman = CreateObject('Chilkat.MailMan')

* Set the SMTP server.
loMailman.SmtpHost = "smtp.comcast.net"

* 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.
