Вы не указали правильный номер раздела для вложенных вложений. Вы должны передать номер раздела на рекурсивном шаге.

function parse_parts($parts, $parentsection = ""){
    foreach($parts as $subsection => $part){
        $section = $parentsection . ($subsection + 1);
        if(isset($part->parts)){

            // some mails have one extra dimension
            $this->parse_parts($part->parts, $section . "." );

        }
        elseif(isset($part->disposition)){
            if(in_array(strtolower($part->disposition), array('attachment','inline'))){
                $data = imap_fetchbody($this->stream, $this->msgno, $section );
                echo 'Getting section ' . $section;
                echo $part->dparameters[0]->value.' '.strlen($data)."\n";
            }
        }
    }
}

(Непроверенный, но должен поступать правильно...)

Загрузка вложений в каталог с IMAP в PHP, беспорядочно работает

Я не знаю конкретно о письмах Mac, но вот какой-то код, который у меня есть, который проходит через каждую из частей, чтобы увидеть, является ли это "ATTACHMENT" и где-то сохраняет файл, поэтому я могу позвонить ему позже.

$body = imap_fetchstructure($box, $i);
$attachments = '';
$att = count($body->parts);
if($att >=2) {
for($a=0;$a<$att;$a++) {
if($body->parts[$a]->disposition == 'ATTACHMENT') {
$file = imap_base64(imap_fetchbody($box, $i, $a+1));
$string = genRandomString();
    if(!file_exists('/var/www/email_store/'.$_SESSION['site_user_id'])) {
        mkdir('/var/www/email_store/'.$_SESSION['site_user_id'].'/');   
    }
    $attachments .= $body->parts[$a]->dparameters[0]->value.'[#]'.$string.',';
    file_put_contents('/var/www/email_store/'.$_SESSION['site_user_id'].'/'.$string,$file);
    }
}
