Where they explained just to add this
FEATURE(
local_lmtp') MAILER(local')I can also see :
FEATURE(
local_lmtp',/usr/sbin/mail.local') MAILER(`local')So, having Dovecot : 10-master.conf service lmtp { unix_listener /var/run/lmtp { mode = 0660 user = mail group = mail } }

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.
