extern crate mime;

use lettre::{EmailTransport, SmtpTransport};
use lettre_email::EmailBuilder;
use std::path::Path;

fn main() {
    let email = EmailBuilder::new()
        // Addresses can be specified by the tuple (email, alias)
        .to(("[email protected]", "Firstname Lastname"))
        // ... or by an address only
        .from("[email protected]")
        .subject("Hi, Hello world")
        .text("Hello world.")
        .attachment(Path::new("Cargo.toml"), None, &mime::TEXT_PLAIN).unwrap()
        .build()
        .unwrap();

    // Open a local connection on port 25
    let mut mailer = SmtpTransport::builder_unencrypted_localhost().unwrap()
                                                                   .build();
    // Send the email
    let result = mailer.send(&email);

    if result.is_ok() {
        println!("Email sent");
    } else {
        println!("Could not send email: {:?}", result);
    }

    assert!(result.is_ok());
}
