I had the same problem with postfix + maildrop, as local(8) 
unconditionally adds the 'From ' header when delivering to an external 
command and upstream did not consider my suggestion to make this 
configurable. The work-arounds I came up with:

1. use 'reformail -f0' as suggested in maildrop(1)

reformail(1):

    -f0
    Any initial blank lines are removed. If the first non-blank line is a 
    "From_" line, it gets converted to a "Return-Path:" header, and any
    existing "Return-Path:" header gets removed. If the message does not 
    start with a "From_" line, the message remains unchanged.

2. adjust the 'maildrop' destination in postfix' master.cf to remove the 
'F' flag.

pipe(8):

    F   Prepend a "From sender time_stamp" envelope header to the 
        message content.  This is expected by, for example, UUCP
        software.

3. Deliver from postfix to a Maildir, bypassing any filtering.

Kind regards,
Andrei
