lettre

NOTE: this readme refers to the 0.10 version of lettre, which is still being worked on. The master branch and the alpha releases will see API breaking changes and some features may be missing or incomplete until the stable 0.10.0 release is out. Use the v0.9.x branch for stable releases.

Features

Lettre provides the following features:

• Multiple transport methods
• Unicode support (for email content and addresses)
• Secure delivery with SMTP using encryption and authentication
• Easy email builders
• Async support

Lettre does not provide (for now):

• Email parsing

Example

This library requires Rust 1.46 or newer. To use this library, add the following to your Cargo.toml:

toml [dependencies] lettre = "0.10.0-beta.4"

```rust,no_run use lettre::transport::smtp::authentication::Credentials; use lettre::{Message, SmtpTransport, Transport};

let email = Message::builder() .from("NoBody nobody@domain.tld".parse().unwrap()) .reply_to("Yuin yuin@domain.tld".parse().unwrap()) .to("Hei hei@domain.tld".parse().unwrap()) .subject("Happy new year") .body(String::from("Be happy!")) .unwrap();

let creds = Credentials::new("smtpusername".tostring(), "smtppassword".tostring());

// Open a remote connection to gmail let mailer = SmtpTransport::relay("smtp.gmail.com") .unwrap() .credentials(creds) .build();

// Send the email match mailer.send(&email) { Ok(_) => println!("Email sent successfully!"), Err(e) => panic!("Could not send email: {:?}", e), } ```

Testing

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

Alternatively only unit tests can be run by doing cargo test --lib.
