What are the potential pitfalls of using SMTP = localhost in the php.ini file for sending emails?

Using SMTP = localhost in the php.ini file for sending emails can cause issues if the SMTP server is not running on the local machine or if the server configuration does not allow sending emails from localhost. To solve this issue, it is recommended to specify a valid SMTP server address in the php.ini file or use the mail function in PHP to send emails directly without relying on an external SMTP server. 

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

// Send email
if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully.";
} else {
    echo "Email sending failed.";
}
