        Some info here, from my limited store of Usenet knowledge:  "From" and 
"Message-ID" are standard headers you receive when you get headers from 
the server.  For others, such as "Path", you have to make a special 
request.

        Both of these headers are only available if you specifically ask the 
server for them; otherwise, they are only downloaded with the body of the 
message.  I *think* you have to ask for them one at a time.  If that's 
true, then grabbing these headers for all messages would dramatically 
increase the time it took to load headers for a newsgroup, because for 
each article, Pan would have to connect to the server and ask for 
extended header info.
        (I recall this from using "suck" -- you *could* write filters or 
killfiles using these headers, but if you did so, you would see "Getting 
XOVER headers" or some such, and this would take a long time.)

        Anyway, knowing this, I can understand why such a thing would not be 
implemented at this stage of Pan's development... though it could be a 
useful thing for those willing to sacrifice the time and bandwidth for 
it.  :)
