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

<p>The interesting thing is IF I am taking off "-" (minus)
from the socket name, everything works just perfect! So
if I change config to:<br>

<p>P.s. I don't mind to use socket without minus on its

awesome<br>
