SMTP NTLM Authentication

See more SMTP Examples

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

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

let mailman = chilkat::MailMan::new();

// Specify your particular mail server's SMTP settings.
mailman.set_smtp_host("smtp.my_mail_server.com");
mailman.set_smtp_port(587);
mailman.set_start_tls(true);

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

let use_current_windows_user = true;

if use_current_windows_user {
    // If you are running on Windows, and you wish for the NTLM credentials of the current logged-on Windows user to be used,
    // set the username and password to the string "default"
    mailman.set_smtp_username("default");
    mailman.set_smtp_password("default");
} else {
    // Explicitly specify the SMTP username/password
    // The SMTP username is your email account username, which is often your email address.
    mailman.set_smtp_username("your_smtp_username_or_email_address");
    mailman.set_smtp_password("your_password");
}

let email = chilkat::Email::new();

email.set_subject("This is a test");
email.set_body("This is a test");
// Don't forget to change this to use your email addresses..
email.set_from("Chilkat Support <support@chilkatsoft.com>");
let _ = email.add_to("Chilkat Admin", "admin@chilkatsoft.com").is_ok();
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

if mailman.send_email(&email).is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

if mailman.close_smtp_connection().is_err() {
    println!("Connection to SMTP server not closed cleanly.");
}

println!("Mail Sent!");
