SMTP Connect and Authenticate

Demonstrates how to connect and then authenticate with an SMTP server. Rust

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

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

mailman.set_smtp_host("smtp.mail.us-west-2.awsapps.com");
mailman.set_smtp_ssl(true);
mailman.set_smtp_port(465);

if mailman.smtp_connect().is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

mailman.set_smtp_username("john@example.com");
mailman.set_smtp_password("the_password");

if mailman.smtp_authenticate().is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

println!("Authenticated!");

println!("{}", mailman.smtp_session_log());
