[Dovecot] socket /var/spool/postfix/private/auth not created

[Reindl Harald]

postfix can hardly create the socket because it
is the *consumer* of it - so dovecot is responsible

as well as other sockets are *not* created at install
but at start time - a socket is not a regular file
and you can compare it to a listening TCP port
