关于邮寄地址的问题！晕！

Georgetown的说明把我给整糊涂了，推荐表格上邮寄地址为

MBA Admissions Office
Box 571148
McDonough School of Business
Georgetown University
Washington, DC 20057-1148 USA

然后，georgetown网站上同时也说：

If you plan on sending your application via overnight or express mail, please be advised that these companies cannot deliver to P.O. Box addresses. Please send your application to the following address:

MBA Admissions Office
3520 Prospect Street, NW
Suite 215
Washington, DC 20007 USA

如果我使用DHL或是FEDEX寄推荐信还有成绩单给该校，到底寄到哪个地址呢？DHL算是express mail吗？

谢谢mariezhu!
