Не удается подключиться: соединение POP3 прервано в ответ

Я пытаюсь загрузить вложения из учетной записи Gmail, но пока не удается.

Я попробовал некоторый фрагмент IMAP, но у меня была эта ошибка:

Cannot connect to Gmail: Can't open mailbox {imap.gmail.com:993/imap/ssl}INBOX: invalid remote specification

Поэтому решил попробовать POP, но дал эту ошибку:

Can't connect: POP3 connection broken in response

Код, который я нашел для POP, был:

if( $mbox = imap_open("{pop.gmail.com:995/pop3}INBOX", "me@gmail", "mypassword")){
$path = "saved_email_docs";
$check = imap_mailboxmsginfo($mbox);
function getmsg($mbox,$mid) {
global $charset,$htmlmsg,$plainmsg,$attachments,$from,$to,$subj,$timages,$path;
$htmlmsg = $plainmsg = $charset = '';
$attachments = array();
// HEADER
$h = imap_headerinfo($mbox,$mid);
// add code here to get date, from, to, cc, subject...
$date = $h->date;
$from = $h->fromaddress;
$to = $h->toaddress;
$subj = htmlspecialchars($h->Subject);
// BODY
$s = imap_fetchstructure($mbox,$mid);
if (!$s->parts)  // simple
getpart($mbox,$mid,$s,0);  // pass 0 as part-number
else {  // multipart: cycle through each part
foreach ($s->parts as $partno0=>$p)
getpart($mbox,$mid,$p,$partno0+1);
}
}

function getpart($mbox,$mid,$p,$partno) {
// $partno = '1', '2', '2.1', '2.1.3', etc for multipart, 0 if simple
global $htmlmsg,$plainmsg,$charset,$attachments,$partid,$last_mail_id,$patterns,$pic,$newstr,$c,$ok,$timages,$subj,$path;
$patterns = array();
$pic =  array();
$image=array();
$data = ($partno) ? imap_fetchbody($mbox,$mid,$partno) : imap_body($mbox,$mid);  // simple
if ($p->encoding==4)
$data = quoted_printable_decode($data);
else if ($p->encoding==3)
$data = base64_decode($data);
// PARAMETERS    // get all parameters, like charset, filenames of attachments, etc.
$params = array();
if ($p->parameters)
foreach ($p->parameters as $x)
$params[strtolower($x->attribute)] = $x->value;
if ($p->dparameters)
foreach ($p->dparameters as $x)
$params[strtolower($x->attribute)] = $x->value;

// ATTACHMENT    // Any part with a filename is an attachment,
// so an attached text file (type 0) is not mistaken as the message.
if ($params['filename'] || $params['name']) {
$partid = htmlentities($p->id,ENT_QUOTES);

// filename may be given as 'Filename' or 'Name' or both
$filename = ($params['filename'])? $params['filename'] : $params['name'];
// filename may be encoded, so see imap_mime_header_decode()
$attachments[$filename] = $data;  // this is a problem if two files have same name
//store id and filename in array
$image[$key] = $filename;

}
//save the attachments in the directory
foreach( $attachments as $key => $val){
$fname = $key;
$fp = fopen("$path/$fname","w");
fwrite($fp, $val);
fclose($fp);
}
// TEXT
if ($p->type==0 && $data) {
// Messages may be split in different parts because of inline attachments,   // so append parts together with blank row.
if (strtolower($p->subtype)=='plain')
$plainmsg .= trim($data)."\n\n";
else
//preg_match_all('/<img[^>]+>/i',$data, $result);
$htmlmsg .= $data."<br><br>";
$charset = $params['charset'];  // assume all parts are same charset
}

// There are no PHP functions to parse embedded messages, so this just appends the raw source to the main message.
else if ($p->type==2 && $data) {
$plainmsg .= $data."\n\n";
}
// SUBPART RECURSION
if ($p->parts) {
foreach ($p->parts as $partno0=>$p2)
getpart($mbox,$mid,$p2,$partno.'.'.($partno0+1));  // 1.2, 1.2.1, etc.
}
}

$attachments = array();
$num_msg = imap_num_msg($mbox);
if($num_msg>0) {
getmsg($mbox,1);
}else {
echo "Sorry!...No Messages in MailBox...<br>";
}

//imap_delete and imap_expunge are used to delete the mail after fetching....Uncomment it if you want to delete the mail from mailbox
//imap_delete($mbox,1);
//imap_expunge($mbox);
imap_close($mbox);

}
else { exit ("Can't connect: " . imap_last_error() ."\n");  echo "FAIL!\n";
}

Есть идеи?
