The secret recipient was a Chinese non-tech company located in Northern VA that is known for its associated with Chinse intelligence.
Presumably the ICIG has the url for wherever the copies of Hillary’s email traffic were being sent (Chinese Non-tech Company X). I continue to wonder whether the NSA or other hi tech spooks can determine whether Company X forwarded the messages on to other servers (by matching metadata, file size, etc.), who owned/operated those servers, where they are (or were) physically, etc.
