No, no.  What you're stipulating here is that /var/run/lmtp is an
executable that communicates LMTP via stdin, whereas dovecot is configured
to communicates LMTP via a socket connection to /var/run/lmtp.  You need
to configure sendmail

 	FEATURE(`local_lmtp',`[IPC]',`FILE /var/run/lmtp')

If you don't need LMTP exposed to the internet (i.e. your front-end MTA
is on the same host as your LMTP), socket connection is probably simpler
and safer than TCP connections.
