小秘回邮件一直是系统自动回复看不懂

给小秘邮箱发了个邮件收到系统自动回复如下：
We have received your e-mail.

Due to a large volume of inquiries we can only respond to those
questions not answered in the Frequently Asked Questions located on
our website (http://www.ece.ucsd.edu/prospective_faq).

If your question is not answered in the FAQ, please reply to this
email (leaving the subject header intact and your original question in
the response) and we will respond individually to your question. We
will only be answering questions that are replies to this e-mail.

General admission requirements are posted at
http://ece.ucsd.edu/gradapply.  Please do not mail any items or
additional materials to UCSD. All materials must be completed
exclusively online using the online application system.

Thank you for your patience.
然后我就按ta说的回复，保持主题不变，把问题写在这封邮件的回复里又发过去了，结果又收到一模一样的系统自动回复。无语了。请教各位我没把邮件内容理解错吧？各位和ucsd的小秘怎么联系的？

回复的邮件的主题应该是RE：XXXXXXXXXXX，这样就不会再收到自动回复了。
