I have a problem with postfix with dovecot ( i already try cyrus-sasl too ). I recive the same error from log when i try log via telnet localhost 25 without SSL. Dovecot its work fine, i test using doveadm -a /var/spool/postfix/private/auth and recive a success, but postfix dont work for some reason. I am using CentOS Stream 9

Postfix version: postfix-3.5.9-24.el9.x86_64

Dovecot version: dovecot-2.3.16-10.el9.x86_64

1. Dovecot 10-master.conf
   ...
2. Postfix smtp-auth
   unix_listener /var/spool/postfix/private/auth { mode = 0600 user = postfix group = postfix }

...

[root@mail postfix]# doveadm auth test -a /var/spool/postfix/private/auth user@domain.com test
passdb: user@domain.com auth succeeded
extra fields:
user=user@domain.com
