Using Local Server

Question

This is confusing. When I did the test emails at work they were fine. All emails and form data were sent and received. When I got home and tried the same experiment I got:
Warning: mail() [function.mail]: SMTP server response: 550 Access denied - Invalid HELO name (See RFC2821 4.1.1.1) in C:\xampp\htdocs\newland\messageSent.php on line 2
I checked my page code at home and also at the office and they are identical.
Office Code:
<?
mail('[email protected]','This is the message subject','This is the message body.');
?>
Home Code:
<?
mail('[email protected]','This is the message subject','This is the message body.');
?>
I then checked both PHP.ini files and they’re identical:
Php.ini file from office:
[mail function]
; For Win32 only.
http://php.net/smtp
SMTP = mail.mail.co.uk
http://php.net/smtp-port
smtp_port = 25
; For Win32 only.
http://php.net/sendmail-from
sendmail_from = [email protected]
php.ini at home:
[mail function]
; For Win32 only.
http://php.net/smtp
SMTP = mail.mail.co.uk
http://php.net/smtp-port
smtp_port = 25
; For Win32 only.
http://php.net/sendmail-from
sendmail_from = [email protected]
I can send and receive emails on my computer at home OK. The only difference between my office computer and home computer is the office computer has windows xp professional installed and my home computer has windows 7 home professional.
Anyone help?

You might edit your home php.ini file to reflect this after you make a backup copy of it:
[mail function]
; For Win32 only.
SMTP = localhost
smtp_port = 25
