   ----- The following addresses had permanent fatal errors -----
<azer0@sss.com>
    (reason: 554 5.3.5 buildaddr: unknown mailer unknown: Unknown error -30988)


Into sendmail, I have only :

MAILER(dovecot)dnl

with 


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

into dovecot ( I removed the lince address = 127.0.0.1 )


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



and sendmail log file  says

Hi,

Please don't mail me personally. I am subscribed to this list and don't want to get mail conversation twice.

And please check to no send HTML formatted mail to mailing lists. Do not top-post either.

After tyding up, here are the files:


*Sendmail :*

   define(`DOVECOT_MAILER_ARGS', `TCP ipv4.localhost 24')dnl
   MAILER(dovecot)dnl

Ok, sure that those entries, especially the MAILER, are located at the end of the sendmail.mc file? Did you afterwards rebuild the sendmail.cf?

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 ?

Yes.

*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

And what is being logged by Sendmail and by dovecot?
