[Jamroom + php mail function]

I am having a problem with my mailer system in my jamroom on godaddy server,  windows hosting.

 

I am running Joomla as well as Jamroom which is running a php mail function.

 

I solved the mail problem in joomla but with Jamroom its giving me the following error:

 

[25-Mar-2009 01:39:10] PHP Warning: mail() [function.mail]: SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in ~\jamroom\include\jamroom-misc.inc.php on line 4406

 

But it works if I just do a simple code:

 

<?php

mail("email@ourdomain.ca", "testsubject",

"testbody");

echo "congrats";

 

I have done my research on google and I couldn't find a definite answer.

 

From what I know its caused my the Bare LFs and something about the (CR) and I have to change  the script to have \r\n for every line of it's header.

 

But what I know which php file I edit and what is a header and what will I have to replace \r\n with??

 

Please help me out here, I got no php programming skills!

 

Thanks in advance.
