#  The mailman object is used for sending and receiving email.
mailman = chilkat.CkMailMan()

#  Any string argument automatically begins the 30-day trial.
success = mailman.UnlockComponent("30-day trial")
if (success != True):
    print "Component unlock failed"
    sys.exit()

#  Set the SMTP server.
mailman.put_SmtpHost("smtp.chilkatsoft.com")

#  Create a new email object
email = chilkat.CkEmail()

email.put_Subject("This email is signed")
email.put_Body("This is a digitally signed mail")
email.put_From("Chilkat Admin <admin@chilkatsoft.com>")
email.AddTo("Chilkat Support","support@chilkatsoft.com")

#  Indicate that the email should be sent signed.
email.put_SendSigned(True)

#  Create an instance of a certificate store object, load a PFX file,
#  locate the certificate we need, and use it for signing.
#  (a PFX file may contain more than one certificate.)
certStore = chilkat.CkCertStore()
#  The 1st argument is the filename, the 2nd arg is the
#  PFX file's password:
success = certStore.LoadPfxFile("chilkat.pfx","myPassword")
if (success != True):
    print certStore.lastErrorText()
    sys.exit()

cert = certStore.FindCertBySubject("Chilkat Software, Inc.")
if (cert == None ):
    print certStore.lastErrorText()
    sys.exit()

#  This example will use the cert from the certStore...
email.SetSigningCert(cert)

#  Render the email to signed-MIME.  This is where the private
#  key is accessed and the signing happens.

signedMime = mailman.renderToMime(email)

#  Now send the already-signed MIME:

fromAddr = "admin@chilkatsoft.com"
recipients = "support@chilkatsoft.com, matt@chilkatsoft.com"
success = mailman.SendMime(fromAddr,recipients,signedMime)
if (success != True):
    print mailman.lastErrorText()
else:
    #  The LastErrorText property provides information
    #  even when successful.
    print mailman.lastErrorText()
    print "Mail Sent!"
