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

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