If you mean ${forward_path}, then as documented that is a local(8)
delivery agent feature, not an lmtp(8) delivery agent feature.
You can kludge around that with "mailbox_transport = dovecot" (or
whatever is the name of the LMTP-to-Dovecot adapter in master.cf).
If some local(8) recipients must not be handled that way, use
mailbox_transport_maps.
