One got our mail redirected to a remote region (5,8)
I believe the answer is:
outer mongolia
'a remote region' is the definition.
(region of Asia)
'one got our mail redirected' is the wordplay.
'redirected' is an anagram indicator.
'one'+'got'+'our'+'mail'='onegotourmail'
'onegotourmail' anagrammed gives 'OUTER MONGOLIA'.
'to' is the link.
(Other definitions for outer mongolia that I've seen before include "Country" , "Former Asian state" .)
