and absolutely NOTHING on Dovecot log file.. and I cannot see anything

Sendmail is using the local mailer as you can see above.

Your Sendmail m4 config is overly complex. For which purpose do you set

LOCAL_DOMAIN(`mbox1.xxxx.net')dnl

And yes, Dovecot is the LMTP server side which provides a TCP socket on port 24. Sendmail is the LMTP client in your case.

To be honest.. I don't know : I thought that the server being mbox1.xxxx.netn, I declared mbox1.xxxx.net in it..

OK I remove it..

You can validate which domains your Sendmail treats as local aka class w by

echo '$=w' | sendmail -bt

In case you want or need to override the Sendmail's host identity you can specify

define(`confDOMAIN_NAME', `example.com')dnl

Hi

I found this... I"'ve made some test.. not very susccesful at the moment, but could it be a possibility to dig up ?

I found this page

http://etutorials.org/server+administration/sendmail/part+i+build+and+install/chapter+4.+configure+sendmail.cf+with+m4/featurelocal_lmtp/

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')

I also try to change chmod lmtp.. 0660 or 640.. nothing is working (

OK, that was just a test :-(

Hi,

This is working out now. So to sum up the situation..

I am using an OS CentOS v8 with Dovecot v 2.3.8 and Sendmail v 8.15.2

Making an LMTP Server  :

on Sendmail ( /etc/mail/sendmail.mc )

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

MAILER(`local')
MAILER(`smtp')

On Dovecot

service lmtp {
  inet_listener lmtp {
    port = 24
  }
  unix_listener /var/run/lmtp {
    group = mail
    mode = 0660
    user = mail
  }
}

protocol lmtp {
  mail_fsync = optimized
  mail_plugins = autocreate quota acl fts fts_solr zlib mail_log notify sieve
  postmaster_address = it@intranet.office.itx
}

Ad that's it really... Hope this will help for the others in the future
