Imap og B-one

Jeg fandt dette eksempel:

<?php
$mbox = imap_open("{pop.domain.xx:143}", "username", "password");

echo "<h1>Mailboxes</h1>\n";
$folders = imap_listmailbox($mbox, "{pop.domain.xx:143}", "*");

if ($folders == false) {
    echo "Call failed<br />\n";
} else {
    while (list ($key, $val) = each($folders)) {
        echo $val . "<br />\n";
    }
}

echo "<h1>Headers in INBOX</h1>\n";
$headers = imap_headers($mbox);

if ($headers == false) {
    echo "Call failed<br />\n";
} else {
    while (list ($key, $val) = each ($headers)) {
        echo $val . "<br />\n";
    }
}

imap_close($mbox);
?>
