It CAN be made give this information. If "Newsgroups:" is present it can  
have two different meanings:

(1) also posted to that group(s).
(2) group to be posted to (i.e. was sent to moderator/gateway).

In the second case, it DOES have a To: header.

But there's no technical need that a To: header matches the envelope  
recipient nor that there is actually a To: header. (Is there?)

So, in the first case, we could just use a BCC: or CC: header instead of  
the To: header to disambiguate the two cases,
where BCC would not appear in the posted version, while CC would.

This way, both the posted and mailed copies are identical (except for  
the BCC).

(( BTW: For the second case, it would be better to transport the article  
in a message/news body part. ))
