Demonstrates how to specify NTLM authentication for sending email via SMTP. Chilkat2-Python

# See Global Unlock Sample for sample code.

mailman = chilkat2.MailMan()

# Specify your particular mail server's SMTP settings.
mailman.SmtpHost = "smtp.my_mail_server.com"

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