dovecot[9075]: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 101: Unknown setting: client

Dosen't work. It should be in 10-master.conf this line. But I don't know why it dosen't work after all

By: Jeff Green

Yea, good ole Dovecot like messing things around to screw people up. Really kills productivity when the do this, and with millions of bytes of advice all refering to old versions you'll never find the answer on Google

The guy who thought it would be blast to change this needs stabbing in the eyes with a pencil!

I had exactly the same problem and the instructions on this page did not help at all. In fact, the instructions on postfix site did not help either.

On our system, here's what helped -

chown postfix:postfix /var/spool/postfix/private/auth

chmod 666 /var/spool/postfix/private/auth

And, in /etc/dovecot/conf.d/10-master.conf (or /usr/local/etc/dovecot/conf.d/10-master.conf) set the config like this -

unix_listener auth-userdb {

mode = 0666

user = postfix

group = postfix

}

# Postfix smtp-auth

unix_listener /var/spool/postfix/private/auth {

mode = 0666

}

Lastly,

/etc/init.d/dovecot restart

The solution posted by easyorange worked for me on Dovecot version 2.0.21 running with Postfix version 2.10.0

By: Alvaro

Thanks, easyorange.

By: Matt

The solution posted by easyorange worked for me with Dovecot v2.2.9. Thank you!

By: Bob Campbell

EasyOrange! This really works.. 2 days trying to figure out why SASL wouldn't authenticate when I could get IMAP working perfectly. I think it was adding this back in that did the trick: unix_listener auth-userdb { mode = 0666 user = postfix group = postfix } I had commented it out thinking "user_listener" was all I needed... BOTH protocols IMAP and SMTP are rocking and authenticating on STARTTLS now... Thanks so much! Bob Campbell PS.. for those out there thinking Cyrus/saslauthd and Postfix are a perfect match are nuts! Postfix is a killer program, but Dovecot really comes on strong in the IMAP department.

As ever the real solution is in the comments - THANK YOU! I have been struggling with this for days.

By: Henry Motu

Thanks, that helps a lot

My server - Debian Squeeze (Debian 6.0) With BIND, Dovecot & Nginx

The following line was absent in my Postfix configuration file:

queue_directory = /var/spool/postfix

By: benjaminbih

Take a look in /etc/dovecot/conf.d/10-masert.conf for:

service auth {

# auth_socket_path points to this userdb socket by default. It's typically
# used by dovecot-lda, doveadm, possibly imap process, etc. Users that have
# full permissions to this socket are able to get a list of all usernames and
# get the results of everyone's userdb lookups.
#
# The default 0666 mode allows anyone to connect to the socket, but the
# userdb lookups will succeed only if the userdb returns an "uid" field that
# matches the caller process's UID. Also if caller's uid or gid matches the
# socket's uid or gid the lookup succeeds. Anything else causes a failure.
#
# To give the caller full permissions to lookup all users, set the mode to
# something else than 0666 and Dovecot lets the kernel enforce the
# permissions (e.g. 0777 allows everyone full permissions).
unix_listener auth-userdb {
    #mode = 0666
    #user =
    #group =
}

# Postfix smtp-auth
#unix_listener /var/spool/postfix/private/auth {
    #mode = 0666
#}

# Auth process is run as this user.
#user = $default_internal_user
}

And change it to fit your needs

None of this worked for me. Not what easyorange wrote, or the original poster. I will also post this as a new Post. One thing I noticed is that if I use the chmod and chown as specified by easyorange, and then restart dovecot, it reverts back to original uid/gid and permissions (root:root). This makes me think perhaps the /etc/dovecot/conf.d/10-master.conf should specify root as the user and group, not postfix.

System: Centos 6.5 (OS: Linux 2.6.32-431.29.2.el6.x86_64 x86_64 CentOS release 6.5 (Final) ), Postfix 2.6.6, Dovcot 2.0.9

This did not all solve my problem, the little extra touch wa found here https://help.directadmin.com/item.php?id=348

If you see this error after Dovecot 2.0.x was installed:

Error: service(pop3-login): listen(::, 110) failed: Address family not supported by protocol Error: socket() failed: Address family not supported by protocol Error: service(pop3-login): listen(::, 995) failed: Address family not supported by protocol Error: socket() failed: Address family not supported by protocol Error: service(imap-login): listen(::, 143) failed: Address family not supported by protocol Error: socket() failed: Address family not supported by protocol Error: service(imap-login): listen(::, 993) failed: Address family not supported by protocol Fatal: Failed to start listeners

it means that Dovecot is trying to bind to an IPv6 interface, but your system doesn't support IPv6. The solution is to tell Dovecot to only listen on an IPv4 interface. You can do this by adding the following to the very top of your /etc/dovecot.conf file

listen = *

The internal default is

listen = *, ::

where the :: is the IPv6 part, hence you don't want to use that in this case.

Para resolver este caso, utilize esta pagina de referencia.

http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL

vi /etc/dovecot/conf.d/10-auth.conf

Al final del Archivo

service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 # Assuming the default Postfix user and group user = postfix group = postfix } }

Se realiza la busqueda de las siguientes variables, en el archivo /etc/postfix/main.cf, sino existen, validar que esten con los valores indicados en cada una, como se mensiona en los siguiente comandos.

cat /etc/postfix/main.cf | grep "smtpd_sasl_path = private/auth"cat /etc/postfix/main.cf | grep "smtpd_sasl_auth_enable = yes"cat /etc/postfix/main.cf | grep "smtpd_sasl_type = dovecot"

Se reinicia los servicios.

/etc/init.d/postfix restart

Validamos que este el archivo, en la siguiente ruta:

ls -l /var/spool/postfix/private/auth

Y asi pude resolver mi caso:

Error: Postfix/Dovecot - warning: SASL: Connect to private/auth failed: No such file or directory

By: tom

adding

client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix }

Just causes

doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf line 24: Unknown setting: client

I am using FreeBSD and followed the SophiMail installation and had this same error and none of these solutions worked but I did fix it.

Of note FreeBSD 11.1 pkg install postfix does not include Mysql support so doesn't work but you can pkg remove the offending packages and recompile with ports and use make config following the directions at http://www.purplehat.org/?page_id=16 but I do not suggest installing Maia as this tutorial is almost 10 years old. dovecot2 is no longer available and is just dovecot..

Recompiling pear with SASL and compile dovecot with the suggested settings at purplehad and install, and cut and paste the config from SophiMail and ta-da, it works. telnet to port 25 now answers with ESMTP greeting and no more SASL errors.

Hello, I stumbled here when trying to fix my Postfix/Dovecot setup after migrating to RHEL 8. In short, none of the instructions worked. I was able to get things working again by following the instructions here: www.linuxbabe.com/redhat/install-dovecot-centos-enable-tls-encryption

In my case, the fix was to add only the following lines:

/etc/dovecot/conf.d/10-master.conf...service auth { unix_listener /var/spool/postfix/private/auth { mode = 0660 user = postfix group = postfix } }

By: Miguel Villanueva

This was the solution for me:

[...] queue_directory = /var/spool/postfix [...]

The suggested recommendations uincluded above did not work.
