Hi,

After tyding up, here are the files:

Sendmail :

define(`DOVECOT_MAILER_ARGS', `TCP $h 24')dnl
MAILER(dovecot)dnl

With: /usr/share/sendmail/mailer/dovecot.m4

Mdovecot,      P=[IPC],
               F=l59DFMPhnu,
               S=EnvFromL/HdrFromL, R=EnvToL/HdrToL,
               U=mail:mail,
               T=DNS/RFC822/SMTP,
               A=TCP $h 24
Do you think that T is correct ?

On Dovecot I have

Mail_location = maildir:/var/spool3/mail/%u:LAYOUT=fs

service lmtp {
  inet_listener lmtp {
    address = 127.0.0.1 ::1
    port = 24
  }
  unix_listener /var/run/lmtp {
    group = mail
    mode = 0660
    user = mail
  }
}

and I am still not be able to receive emails into the inbox

3) on /var/spool3/mail/<user1>, I have

Here is my _*sendmail config*_

define(`confLOCAL_MAILER', `local_lmtp')dnl
dnl ############################  FIN OPENDKIM ######
dnl ###### boost traitement ############"dnl
FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl
dnl # define(`confCONNECTION_RATE_THROTTLE',2800)dnl
FEATURE(local_procmail, `', `procmail -t -Y -a $h -d $u')dnl
*FEATURE(`local_lmtp')*
MAILER(local)dnl
MAILER(smtp)dnl
MAILER(procmail)dnl
MAILER(dovecot)dnl   ->maybe totally useless if I declare : MAILER( local )

Hm, this Sendmail config part looks like a mess.

You need a proper MAILER definition which tells Sendmail to use LMTP. And remove those mailers you don't make use of like procmail.

Have a look at the cyrusv2 mailer definition and adopt it for dovecot.
