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

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

Nothing definitive. It's just that the socket expects certain type of input, this is comparable of trying to configure postfix to speak to imap-master socket. There is no reason why it should work.
