Mail RP - to clarify FOIA status request letter Condeleeza Rice

Dear Sir/Madam, 

In 2013 I handed in a FOIA request. I had requested to communicate by mail, since I live in Brussels/Europe. 
I did not hear anything back. 

Now this FOIA overview was send to me by someone who found my name on it. 
It states 'other reasons', and it is not clear to me what that means. 

Could you please clarify? 

Thank you in advance, 

Roelie Post
