Quite right.  See my follow up posting with corrections.  I didn't read
the RFC's for this information.  I simply looked at the actual headers of
news and mail.  Mail consistantly has "From " on the first line and news
has "Path:" on the first line, both in the first 5 characters.  My guess
is the RFC's somewhere define this. 

BTW, has anyone had any problem compiling that code?  Just curious.

Cheers!
