How can one troubleshoot errors like "Der Host 'pop3 localhost' wurde nicht gefunden" when trying to access emails through PHP?

The error "Der Host 'pop3 localhost' wurde nicht gefunden" indicates that the POP3 host 'localhost' could not be found. To solve this issue, ensure that the correct POP3 host address is used in the PHP script. Additionally, check the server configuration to ensure that the POP3 service is running and accessible. 

<?php
$pop3_server = 'mail.example.com'; // Update this with the correct POP3 host address
$port = 110;
$username = 'your_email@example.com';
$password = 'your_password';

$inbox = imap_open("{".$pop3_server.":".$port."/pop3}", $username, $password);

if ($inbox) {
    echo "Connected to POP3 server successfully!";
    // Further actions like fetching emails can be performed here
    imap_close($inbox);
} else {
    echo "Failed to connect to POP3 server. Check your configuration.";
}
?>
