Sending mails with attachment via NodeJS

Try with nodemailer, for example try this:

  var nodemailer = require('nodemailer');
  nodemailer.SMTP = {
     host: 'mail.yourmail.com',
     port: 25,
     use_authentication: true,
     user: '[email protected]',
     pass: 'somepasswd'
   };

  var message = {   
        sender: "[email protected]",    
        to:'[email protected]',   
        subject: '',    
        html: '<h1>test</h1>',  
        attachments: [  
        {   
            filename: "somepicture.jpg",    
            contents: new Buffer(data, 'base64'),   
            cid: cid    
        }   
        ]   
    };

finally, send the message

    nodemailer.send_mail(message,   
      function(err) {   
        if (!err) { 
            console.log('Email send ...');
        } else console.log(sys.inspect(err));       
    });

Yes, it is pretty simple, I use nodemailer: npm install nodemailer --save

var mailer = require('nodemailer');
mailer.SMTP = {
    host: 'host.com', 
    port:587,
    use_authentication: true, 
    user: '[email protected]', 
    pass: 'xxxxxx'
};

Then read a file and send an email :

fs.readFile("./attachment.txt", function (err, data) {

    mailer.send_mail({       
        sender: '[email protected]',
        to: '[email protected]',
        subject: 'Attachment!',
        body: 'mail content...',
        attachments: [{'filename': 'attachment.txt', 'content': data}]
    }), function(err, success) {
        if (err) {
            // Handle error
        }

    }
});

Personally i use Amazon SES rest API or Sendgrid rest API which is the most consistent way to do it.

If you need a low level approach use https://github.com/Marak/node_mailer and set up your own smtp server (or one you have access too)
