SMTP NTLM Authentication

See more SMTP Examples

Demonstrates how to specify NTLM authentication for sending email via SMTP. B4X

Dim success As Boolean = False

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

Dim mailman As ChilkatMailMan
mailman.Initialize("mailman")

'  Specify your particular mail server's SMTP settings.
mailman.SmtpHost = "smtp.my_mail_server.com"
mailman.SmtpPort = 587
mailman.StartTLS = True

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