Hello,

<?php
$mbox = imap_open("{pop.server.com:110/pop3}INBOX", "[e-mail]", "password");

$er = imap_errors();

if($er[0]) {
echo $er[0]."<br />";
}

echo "<h1>Mailboxes</h1>\n";
$folders = imap_listmailbox ($mbox, "{pop.server.com:110}", "*");

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";
