Postfix sasllogin失败未find任何机制

以下链接： http ://flurdy.com/docs/postfix/与posfix，courier，MySql和sasl给了我一个具有imapfunction的Web服务器工作正常，但是当我去login到服务器发送消息使用相同的用户名和密码连接的IMAP服务器它拒绝我的login到SMTP服务器。 如果我不指定外发邮件服务器的login，那么它会发送消息就好了。 后缀的日志中的错误是：

Jul 6 17:26:10 Sj-Linux postfix/smtpd[19139]: connect from unknown[10.0.0.50] Jul 6 17:26:10 Sj-Linux postfix/smtpd[19139]: warning: SASL authentication failure: unable to canonify user and get auxprops Jul 6 17:26:10 Sj-Linux postfix/smtpd[19139]: warning: unknown[10.0.0.50]: SASL DIGEST-MD5 authentication failed: no mechanism available Jul 6 17:26:10 Sj-Linux postfix/smtpd[19139]: warning: unknown[10.0.0.50]: SASL LOGIN authentication failed: no mechanism available 

我检查了所有用户名和密码为MySQL。 有什么可能会出错？

编辑：

这里是一些其他的信息：

• 在postfix中重命名邮件程序守护进程
• Postfix证书validation失败的smtp.gmail.com
• 无法解释邮件日志DNS错误
• 简单的SMTP服务器，用于基于别名的转发
• Postfix：处理来回地址和收件人地址不合法的退回邮件？

为postfix，courier和sasl安装libraires：

 aptitude install postfix postfix-mysql aptitude install libsasl2-modules libsasl2-modules-sql libgsasl7 libauthen-sasl-cyrus-perl sasl2-bin libpam-mysql aptitude install courier-base courier-authdaemon courier-authlib-mysql courier-imap courier-imap-ssl courier-ssl 

这里是我的/etc/postfix/main.cf
