PHP电子邮件在WIMP上失败

I've got a WordPress site with a contact form that works fine on my MAMP environment, but when I publish to my clients WIMP server I get a failure.

• I am not at all familiar with WIMP environments- how does one go about checking PHP error logs
• Offhand, are there issues with PHP emailing on WIMP that would be causing this?

Code:

<?php 

if ($_POST["contact_name"]<>'') { 
    $ToEmail = 'me@domain.com'; 
    $EmailSubject = 'New contact message';  
    $mailheader = "From: ".$_POST["contact_email"]."
";  
    $mailheader .= "Reply-To: ".$_POST["contact_email"]."
"; 
    $mailheader .= "Content-type: text/html; charset=iso-8859-1
";  
    $MESSAGE_BODY = "<b>Name:</b> ".$_POST["contact_name"]."<br>";  
    $MESSAGE_BODY .= "<b>Email:</b> ".$_POST["contact_email"]."<br>";
    mail($ToEmail, $EmailSubject, $MESSAGE_BODY, $mailheader) or die ("Failure"); 

?> 
<h4>Your message was sent. We will be in touch with you shortly.</h4>
<?php 
} else { 
<form id="contact-form" name="contact" method="post" action="#">
<label for="contact-name">Name *</label>
<input type="text" id="contact-name" name="contact_name" tabindex="1" class="required"/>
<label for="contact-email">Email</label>
<input type="text" id="contact-email" name="contact_email" tabindex="2" class="email" />
<input type="submit" id="contact-submit" name="contact_submit" value="" tabindex="8" />
</form>
<?php 
}; 
?>

Windows does not have a built in email server like unix type OSs tend to have. You need to configure php.ini to add SMTP server information through which to relay email.

The PHP manual page for the `mail()' function details a number of Windows-specific points. However, the main points which could affect you are in this section: (to quote)

The Windows implementation of mail() differs in many ways from the Unix implementation. First, it doesn't use a local binary for composing messages but only operates on direct sockets which means a MTA is needed listening on a network socket (which can either on the localhost or a remote machine).

Second, the custom headers like From:, Cc:, Bcc: and Date: are not interpreted by the MTA in the first place, but are parsed by PHP.

As such, the to parameter should not be an address in the form of "Something <someone@example.com>". The mail command may not parse this properly while talking with the MTA.

There are a few other things to consider as well; please read the manual page for more.

Hope that helps.
