How can PHP mail functions be adjusted to work on a Microsoft-IIS/7.5 server without a sendmail server?

The PHP mail function can be adjusted to work on a Microsoft-IIS/7.5 server without a sendmail server by configuring the SMTP settings in the php.ini file. You can set the SMTP server address and port in the php.ini file to route the mail through an SMTP server that is accessible from the IIS server. 

ini_set('SMTP', 'smtp.yourserver.com');
ini_set('smtp_port', 25);

$to = 'recipient@example.com';
$subject = 'Test Email';
$message = 'This is a test email';

mail($to, $subject, $message);
