当我将垃圾邮件移到我的收件箱时，它会再次使用imap程序为雅虎重新发送垃圾邮件？

<?php

$mbox = imap_open("{imap.mail.yahoo.com:993/imap/ssl}Bulk Mail",$mailuser,$mailpass) 
      or die("can't connect: ".imap_last_error()); 
.
imap_mail_move($mbox,$messageset,"INBOX"); 
@imap_expunge($mbox);
imap_close($mbox);

?>

Its moving Successfully...
