特点：不需要设置SMTP服务器，直接发送邮件（适合用来发送no-reply邮件，发送垃圾邮件也可以， 凸）

使用

sendmail = require('sendmail').sendmail;

sendmail({
    from: 'no-reply[@yourdomain](/user/yourdomain).com',
    to: 'test[@qq](/user/qq).com, test[@sohu](/user/sohu).com, test[@163](/user/163).com ',
    subject: 'test sendmail',
    content: 'Mail of test sendmail ',
  }, function(err, reply) {
    console.log(err && err.stack);
    console.dir(reply);
});
