In cases where PHP mail function returns true but emails are not received, what steps can be taken to resolve the issue?

If the PHP mail function returns true but emails are not being received, it could be due to various reasons such as spam filters blocking the email, incorrect email settings, or server configuration issues. To resolve this, you can try setting proper headers, checking spam folders, ensuring the email address is correct, and contacting your hosting provider for further assistance.

// Example PHP code snippet to set headers and send an email
$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: sender@example.com\r\n";
$headers .= "Reply-To: sender@example.com\r\n";
$headers .= "X-Mailer: PHP/" . phpversion();

if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully";
} else {
    echo "Failed to send email";
}
