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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.MailMan')
$mailman = new COM("Chilkat.MailMan");

// Specify your particular mail server's SMTP settings.
$mailman->SmtpHost = 'smtp.my_mail_server.com';
$mailman->SmtpPort = 587;
$mailman->StartTLS = 1;

// 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.

    // If you are running on Windows, and you wish for the NTLM credentials of the current logged-on Windows user to be used,

    $mailman->SmtpUsername = 'default';
    $mailman->SmtpPassword = 'default';
