550 Relay denied when tring to send email with PHP, unable to use Xmail for php on windowsXP

I use a Apache server installed on a Windows XP platform and PHP5. I recently installed xmail-1.22.win32bin to serve as an SMTP server to send emails using a PHP mailing script. When ever I try sending email from my computer, I receive the below error message in my browser;

Warning: mail() [function.mail]: SMTP server response: 550 Relay denied in E:\Softwares\xampplite\htdocs\mail\ourown\sendem.php on line 78

where E:\Softwares\xampplite\htdocs\mail\ourown\sendem.php is the link to my php mailing script. and E: is the drive where I have my operating system and my apache server installed and xmail at E:\MailRoot

I configured Xmail with instructions from the readme file for NT/Win2K and did it all to number 16. I did'nt do any other configuration because i am not using xmail to retrive email or for email account I only needed it as a mail server to sedn email with my php script form my computer.
My request if for assitance so as to enable me resolve the issue and send email from my web server installed in my pc with ease.


Note: my php mailing script has worked perfectly on diffrent web servers.

Add this to smtprelay.tab:
"127.0.0.0" "255.255.255.0"

I use Windows XP service pack 2, with apache server and PHP5, i use xmail-1.22.win32bin I have installed the Xmail que manger. when i try sending email the messages never delivers. It is always error sending in the que manager subject: Error sending message [1154692636156.6116.1.today]from[xmailserver.test] from root@xmailserver.text. Also, my messages are always frozen and never delivers. When I use the spool file inspector this is what i find

For the Diagnosis:
SYNTAX_FROM

Possible reasons:
- The sending address is malformed.
- The sending address is unbalanced. This means a missing opening or closing > or ).
- The sending address is blocked by the recipient's SMTP
- The sender's domain cannot be resolved by the recipient's DNS

Furthermore, If I put a recipient addresses in the TO: or CC: field this is the response i get:
Warning: mail() [function.mail]: SMTP server response: 501 Syntax error in forward path in E:\Softwares\xampplite\htdocs\mail\ourown\sendem.php on line 78 this dosent happen with Bcc:
I do not know how to resolve the issue so i decided to seek help from this forum

The address is malformed for the yahoo server. It accepts only the email address in the MAIL FROM, but not the user's name:

So this is not a XMail problem, your script needs to be adapted to this ...

I do not understand your response how I can fix the problem

so I decided to post my script that sends the email and this script has work well on servers over the internet.

I do not know where the problenm comes from in my script

Change this

to that:
