PHP Mail() on IIS problem

[kool_samule]

Hi  Chaps,

 

I've been searching on Google for ages now and can't seem to find a solution that works.

 

I have a mail script:

$to = '[email protected]';
$subject = "You've got Mail!"; 
$message = 'This is a test Email';
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: Webmaster <[email protected]>' . "\r\n";
$sent = mail("$to", "$subject", "$message", "$headers") ; 

 

This code is tried and tested on a UNIX server and sends to Hotmail accounts.

 

However, I had to change this:

$headers .= 'From: Webmaster <[email protected]>' . "\r\n";

to this:

$headers .= 'From: [email protected]' . "\r\n";

to even get mail() to work on my work IIS server, but it doesn't send to Hotmail accounts.

 

I thought that Hotmail may have blacklisted our work DNS settings, but I can send emails from my work email account to Hotmail account without any problems and IIS and MS Exchange on the same server. . . . .

 

Is there something else I can try or look for as this is doing my nut in?
