SMTP NTLM Authentication

See more SMTP Examples

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

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

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

    const mailman = try chilkat.MailMan.init();
    defer mailman.deinit();

    // Specify your particular mail server's SMTP settings.
    mailman.setSmtpHost("smtp.my_mail_server.com");
    mailman.setSmtpPort(587);
    mailman.setStartTLS(true);

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

        mailman.setSmtpUsername("default");
        mailman.setSmtpPassword("default");
    } else {
