Send Email With Attachments

See more SMTP Examples

Demonstrates how to send an email with attachments. Rust

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

// The mailman object is used for sending (SMTP) and receiving (POP3) email.
let mailman = chilkat::MailMan::new();

// Set the SMTP server.
mailman.set_smtp_host("smtp.my-tls-mail-server.com");

// Set the SMTP login/password (if required)
mailman.set_smtp_username("MY_SMTP_USERNAME");
mailman.set_smtp_password("MY_SMTP_PASSWORD");

// Connect to SMTP port 465 using TLS.
mailman.set_smtp_ssl(true);
mailman.set_smtp_port(465);

// Create a new email object
let email = chilkat::Email::new();

email.set_subject("This is a test");
email.set_body("This is a test");
email.set_from("Chilkat Support <support@chilkatsoft.com>");
let _ = email.add_to("Chilkat Admin", "admin@chilkatsoft.com").is_ok();
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

// Add some attachments.
// The AddFileAttachment method returns the value of the content-type it chose for the attachment.
let Ok(mut content_type) = email.add_file_attachment("qa_data/jpg/starfish.jpg") else {
    println!("{}", email.last_error_text());
    return;
};

content_type = email.add_file_attachment("qa_data/pdf/fishing.pdf").unwrap_or_default();
if !email.last_method_success() {
    println!("{}", email.last_error_text());
    return;
}

// Call SendEmail to connect to the SMTP server and send.
// The connection (i.e. session) to the SMTP server remains
// open so that subsequent SendEmail calls may use the
// same connection.  
if mailman.send_email(&email).is_err() {
    println!("{}", mailman.last_error_text());
    return;
}

if mailman.close_smtp_connection().is_err() {
    println!("Connection to SMTP server not closed cleanly.");
}

println!("Mail with attachments sent!");
