Example

This library requires Rust 1.20 or newer. To use this library, add the following to your Cargo.toml:

[dependencies]
lettre = "0.9"
lettre_email = "0.9"

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

let email = EmailBuilder::new()
    // Addresses can be specified by the tuple (email, alias)
    .to(("user@example.org", "Firstname Lastname"))
    // ... or by an address only
    .from("user@example.com")
    .subject("Hi, Hello world")
    .text("Hello world.")
    .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());

Testing

The lettre tests require an open mail server listening locally on port 2525 and the sendmail command.
