Dovecot has some special socket names, auth-userdb is one of those.

Hi
What you have suggested works.
service auth { unix_listener /var/spool/postfix/private/auth { user = postfix group = postfix mode = 0600 } }
This works as well:
service auth { unix_listener /var/run/dovecot/auth { owner = postfix group = postfix mode = 0600 } }
And this works as well:
service auth { unix_listener /var/run/dovecot/auth-test-test { owner = postfix group = postfix mode = 0600 } }
And only when socket has name "auth-userdb"
service auth { unix_listener auth-userdb { owner = postfix group = postfix mode = 0600 } }
it doesn't.
When socket name is "auth-userdb" I can see in the log:

Ah i see.
try this:
dovecot.conf:
service auth { unix_listener /var/spool/postfix/private/auth { owner = postfix group = postfix mode = 0600 } }
postfix.conf:
smtpd_sasl_path = private/auth

Hello
Yes, please find my postfix config:
smtpd_sasl_type = dovecot #smtpd_sasl_path = /var/run/dovecot/auth smtpd_sasl_path = /var/run/dovecot/auth-userdb smtpd_sasl_auth_enable = yes smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
As I mentioned if I remove minus from socket name everything works perfect. Thanks

Did you tell postfix it's talking to dovecot?

Hi guys.
I am getting strange error:

The interesting thing is IF I am taking off "-" (minus) from the socket name, everything works just perfect! So if I change config to:
service auth { unix_listener blabla { mode = 0600 user = postfix group = postfix } }

P.s. I don't mind to use socket without minus on its name. But this looks really strange. Thanks. You are awesome
