在过去的6个小时左右，我一直在尝试对此进行sorting，这是我正面临的错误信息（运行CentOS x64）：
/var/log/maillog ：

我也安装了鸽子，我可以通过MySQL身份validation接收电子邮件。
问题是当我试图使用SMTP发送电子邮件。
一些configuration文件：
/etc/postfix/main.cf ：

我会build议直接使用cyrus-sasl-sql，而不使用saslauthd。 像下面这样：
# 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
