To get started, add the SMTPKitten dependency:

.package(url: "https://github.com/joannis/SMTPKitten.git", from: "1.0.0"),

And add it as a dependency of your target:

.product(name: "SMTPKitten", package: "SMTPKitten"),

Create a connection

try await SMTPClient.withConnection(
    to: "localhost",
    port: 1025,
    ssl: .insecure
) { client in
    // 1. Authenticate
    try await client.login(
        user: "xxxxxx",
        password: "hunter2"
    )
    
    // 2. Send emails
}

Sending Emails

Before sending an email, first contruct a Mail object. Then, call sendMail on the client.

let mail = Mail(
    from: MailUser(name: "My Mailer", email: "noreply@example.com"),
    to: [MailUser(name: "John Doe", email: "john.doe@example.com")],
    subject: "Welcome to our app!",
    content: .plain("Welcome to our app, you're all set up & stuff.")
)

try await client.sendMail(mail)

The Mail.Content type supports various other types of information including HTML, Alternative (HTML with Plaintext fallback) and multipart.
