# 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 = chilkat2.MailMan()

# Set the SMTP server.
mailman.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.
cert = chilkat2.Cert()
success = cert.LoadFromFile("cknotes.cer")
if (success != True):
    print(cert.LastErrorText)
    sys.exit()

# Create a new email object
email = chilkat2.Email()

email.Subject = "This email is encrypted"
email.Body = "This is a digitally encrypted mail"
email.From = "Chilkat Support <support@chilkatsoft.com>"
success = email.AddTo("Chilkat Blog","admin@cknotes.com")

# Indicate that the email is to be sent encrypted.
email.SendEncrypted = True

# Specify the certificate to be used for encryption.
success = email.SetEncryptCert(cert)

success = mailman.SendEmail(email)
