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
}
}
I wrote FEATURE(`localhost_lmtp',`/var/run/lmtp')
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.
