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: 'info@youdomain.com',
     pass: 'somepasswd'
   };

  var message = {   
        sender: "sender@domain.com",    
        to:'somemail@somedomain.com',   
        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));       
    });
