What common error message might indicate an issue with sending emails via PHP?

One common error message that might indicate an issue with sending emails via PHP is "Warning: mail(): Failed to connect to mailserver". This error typically occurs when the SMTP server settings are not configured correctly in the PHP code. To solve this issue, you need to ensure that the SMTP server settings are correctly configured in your PHP script. This includes setting the 'ini_set' function to specify the 'sendmail_from' and 'SMTP' values. Additionally, make sure that the SMTP server address, port, username, and password are correctly provided in the 'mail' function. 

<?php
ini_set("sendmail_from", "your_email@example.com");
ini_set("SMTP", "smtp.example.com");

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";
$headers = "From: your_email@example.com";

if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully!";
} else {
    echo "Failed to send email. Please check your server settings.";
}
?>
