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

mailman = chilkat.CkMailMan()

# Specify your particular mail server's SMTP settings.
mailman.put_SmtpHost("smtp.my_mail_server.com")
mailman.put_SmtpPort(587)
mailman.put_StartTLS(True)

# This assumes you know your SMTP server supports NTLM authentication.
# To explicitly request NTLM authentication, set the SmtpAuthMethod property = "ntlm".
mailman.put_SmtpAuthMethod("ntlm")

# Note: Normally you should avoid setting the SmtpAuthMethod.
# SMTP servers tell the connecting client the authentication methods it will accept when the initial connection is made.
# Chilkat will automatically use this information to select and use the most secure auth method supported by the server.
