Test script:
---------------
$imapStream = imap_open($imapPath, $login, $password);

$mailIds = imap_search($imapStream, 'ALL', SE_UID);

$mailId = array_shift(mailIds);

$mailStructure = imap_fetchstructure($imapStream, $mailId, FT_UID);

var_dump($mailStructure);
var_dump($mailStructure->parts[1]->dparameters[0]->value);
var_dump(urldecode('%D0%BF%D1%83%D1%81%D1%82%D0%BE%D0%B9%20%D1%84%D0%B0%D0'));
