Node Mail

This SMTP client helps you send email safely and easily using Node.JS. It supports TLS and auth-login so you can send through gmail. It also implements sanity checks to safeguard against header injection attacks.

Installation

Use NPM to install:

npm install mail

Sending Mail

The Mail class encapsulates connection settings and can be used as a safe, high-level mailer.

var mail = require('mail').Mail({
  host: 'smtp.gmail.com',
  username: '[e-mail]',
  password: '**password**'
});

Use the mailer to send messages:

mail.message({
  from: '[e-mail]',
  to: ['[e-mail]'],
  subject: 'Hello from Node.JS'
})
.body('Node speaks SMTP!')
.send(function(err) {
  if (err) throw err;
  console.log('Sent!');
});

Mail(options)

Create a new mailer that can be used to send messages. Common options include:

• host: server hostname
• username: user for server authentication
• password: password for server authentication,

Other options:

• secure: true, false, or crypto credentials (default: true)
• port: server listens on this port (default: 587 or 25)
• domainName: the domain of the sender (default: os.hostname())
• mimeTransport: 7BIT or 8BITMIME (default: 8BITMIME)

Mail.message(headers)

Begin a MailTransaction. The headers object may contain any any SMTP headers. When the message is formatted, email addresses are validated, header names are title-cased, and header values escaped to prevent injection. A Date header is automatically added.

An email address may be an array, a single address, or a string with command-separated addresses. Individual addresses may be bare or in the format "Display Name" <[e-mail]>.

MailTransaction.body(text)

Add a body to a mail transaction. Long lines are automatically wrapped.

MailTransaction.send(callback)

Connect to the server, transmit the message, and quit. The callback should be in the form function(err, message) { ... }. Upon success, err is null and message is set to the Message object that was sent to the server.

Compatibility

Node Mail has been tested against qmail and gmail using Node version v0.4.3. A working subset of these RFCs are supported:

• Internet Message Format
• Simple Mail Transfer Protocol
• Authentication Extension
• SMTP Transport Layer Security
• 8-bit MIME Transport

There is not currently direct support for multipart messages or attachments, although node-mail will send messages in this format if they're build manually.
