When transitioning to PHP5, what considerations should be made regarding existing scripts that utilize the mail() function, especially on Windows servers?

When transitioning to PHP5, one consideration to make regarding existing scripts that utilize the mail() function on Windows servers is that the default configuration may not be set up to send emails properly. To solve this, you can configure PHP to use an SMTP server to send emails instead of relying on the local mail server. 

// Set the SMTP server configuration
ini_set("SMTP", "mail.example.com");
ini_set("smtp_port", "25");

// Send email using the SMTP server
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com";

// Send the email
mail($to, $subject, $message, $headers);
