From:, Mail, and sendmail

Unfortunately, not everyone uses path aliasing either (the uw for one).
Not that we wouldn't like to, its just that we never got the software.

I sit corrected here.

Another plan of attack:  uucp sites *should* update the UN*X 'From ' line
correctly.  A BSD site will probably also be running rmail (the 4.2 rmail
is even portable to 2.9) and will reconstruct a 'correct' 'From ' line from
those contained in the header.  It could easily be modified to fix the 'From:'
line also.  Obviously, if some site messes up the 'From ' line, there isn't
much hope here either.  A non-BSD site just takes the address in the 'From '
line and replies to this address, doesn't it (assuming the site runs some
kind of UN*X)?  This should also get the reply to the right place.
