fsock error

Warning: fsockopen(): unable to connect to 147.202.69.2:25 in /home/domain/public_html/test/socktest.php on line 2
Connection refused (111)

This is a very simple script, it just tries to connect to port 25 (SMTP) of the host:

script
Code: 
<?php
$fp = fsockopen("147.202.69.2", 25, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
    echo "Connected OK";
    fclose($fp);
}
?>
What could cause this?
