This is not true - as mentioned in the summary from the last discussion,
if the address on the 'From: ' line exactly matches the envelope sender
address, sendmail *will* attempt to add the Full name if/as found in the
passwd file. I.e. if the client uses the <address> form for the 'From: '
line, as in:

Dq$x <$g>

the server will try to do the Full name lookup, with the caveats
mentioned (i.e. sender must be considered "local" on the server etc).
