Show us the configuration of postfix. How do you deliver the mail
to Cyrus' lmtp socket (i.e what 'transport' do you use) ?
My config has in relay_domains and I use
relay_transport to point to the ltmp socket.
  Alternatively you could use a transport map ( see transport_maps)
and not touch the relay_transport and in the map file you just
point to the lmtp socket.
