How can setting up a local mail relay server help in resolving SMTP email sending issues in PHP scripts?

Setting up a local mail relay server can help in resolving SMTP email sending issues in PHP scripts by providing a more reliable and secure way to send emails. By configuring PHP to use the local mail relay server, you can ensure that emails are properly authenticated and delivered without being blocked by spam filters. 

// Set the SMTP server configuration in PHP
ini_set("SMTP", "localhost");
ini_set("smtp_port", "25");

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

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