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

CkoMailMan *mailman = [[CkoMailMan alloc] init];

// 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.
