Sending HTML in Email

Hi,

I am trying to send Html in an Email through the following source code:

var email = require("./mailer/lib/node_mailer");

email.send({
host : "smtp.xyz.com", // smtp server hostname
port : "25", // smtp server port
ssl: false, // for SSL support - REQUIRES NODE v0.3.x OR HIGHER
domain : "xyz.com", // domain used by client to identify itself to server
to : "user@abc.com",
from : "info@xyz.com",
subject : "Hello World",
body: "

Hello! This is a test of the node_mailer.

<a href = "www.google.co.in">",
authentication : "login", // auth login is supported; anything else is no auth
username : "info@lfn.com", // username
password : "Pornichet", // password
debug : true,
html : true
},
function(err, result){
if(err){ console.log(err); }
});

On executing the script, i get the following error message:

Object true has no method 'replace'
