Postfix + SASLAUTHD + MySQL認証の問題

私は過去6時間ほどこれを整理しようとしてきました、これは私が直面しているエラーメッセージです（CentOS x64を実行しています）：

Dovecotもインストールしていて、MySQL認証を介してメールを受信できます。

問題は、SMTPを使用して電子メールを送信しようとしているときです。

いくつかの設定ファイル：

Saslauthdを使用せずにcyrus-sasl-sqlを直接使用することをお勧めします。次のようなもの：

# cat /usr/lib64/sasl2/smtpd.conf
pwcheck_method: auxprop
mech_list: PLAIN LOGIN CRAM-MD5
auxprop_plugin: sql
sql_usessl: no
sql_engine: mysql
sql_hostnames: localhost
sql_user: mail_admin
sql_database: mail
sql_passwd: password
sql_select: select password from users where email = '%u@%r'
log_level: 3
