I ran into a similar problem recently.

It was explained to me that if you explicity define the transport for 
lmtp in "transports" you then disable piping to commands in Postifx (and 
a few other issues).   What you need to do is comment out that 
definition in "transports" (presuming this is the case here) and define:

mailbox_transport = lmtp:unix:/var/imap/socket/lmtp

(modify as appropriate for your system)

And then the pipe-to-commands should work.   There are more specifics 
about why this is so - but that's what solved this for me.
