Warning in the logs of Postfix: "restriction NNN ignored: no SASL support". But it does have SASL support

I have postfix + dovecot + pgsql. All has been working. Recently I've changed something in the config to combat spam. Now I see this in the logs: localhost postfix/smtpd: warning: restriction `reject_authenticated_sender_login_mismatch' ignored: no SASL support localhost postfix/smtpd: warning: restriction `reject_unauthenticated_sender_login_mismatch' ignored: no SASL support localhost postfix/smtpd: warning: restriction `reject_authenticated_sender_login_mismatch' ignored: no SASL support localhost postfix/smtpd: warning: restriction `reject_unauthenticated_sender_login_mismatch' ignored: no SASL support But! $ postconf -a cyrus dovecot And $ ldd /usr/sbin/postfix | grep sasl libsasl2.so.3 => /usr/lib/libsasl2.so.3 (0x00007f9508e75000) If I remember correctly, I installed postfix via "pacman". Why the warning and how to fix it? upd1: sudo postconf | grep -i smtpd_sasl smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = no smtpd_sasl_exceptions_networks = smtpd_sasl_local_domain = smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous, noplaintext smtpd_sasl_service = smtp smtpd_sasl_tls_security_options = noanonymous smtpd_sasl_type = dovecot upd2: in master.cf I've found this: smtp inet n - n - - smtpd -o smtpd_sasl_auth_enable=no Can this be the reason? upd3: also: submission inet n - y - - smtpd -o syslog_name=postfix/submission -o smtpd_tls_security_level=encrypt -o smtpd_enforce_tls=yes -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_sasl_security_options=noanonymous -o milter_macro_daemon_name=ORIGINATING -o smtpd_sasl_local_domain=$myhostname -o smtpd_client_restrictions=permit_sasl_authenticated, reject -o smtpd_recipient_restrictions=permit_sasl_authenticated, reject
