I am also getting this exact same error in a new postfix server I
setup. Changing the command from lmtp to smtp fixes it for me as well.
The lmtp and smtp files are the same inode (this is stretch 3.1.4-4)
# ls -il /usr/lib/postfix/sbin/{s,l}mtp
30169 -rwxr-xr-x 2 root root 121408 Jan 25 15:03 /usr/lib/postfix/sbin/lmtp
30169 -rwxr-xr-x 2 root root 121408 Jan 25 15:03 /usr/lib/postfix/sbin/smtp
It looks like the lmtp->smtp change was not reverted in the debian
patches, so only upgrades were fixed and new installs are still broken:
