我试图使用Dovecot + Postfix + Mysql到目前为止一切正常。 由于从Debian 6升级到7，我无法发送邮件。 接收仍然是可能的。
/var/log/mail.log
Oct 22 15:21:24 XXXXXXXX postfix/smtpd[17765]: warning: XXXXX: SASL PLAIN authentication failed: no mechanism available 我试图研究这个错误，并发现了一些事情，迄今为止并没有真正的帮助。
这是我postconf -n的输出

和我的dovecot.conf

在升级之后，我对dovecot.conf进行了修改，使之与已安装的dovecot的新版本一起工作。 我认为在部分服务auth中的东西是错误的，但很多谷歌search后仍然没有find。
你能提供进一步的帮助吗？
所以，你已经告诉dovecot设置这个服务的身份validation：
'unix_listener / var / spool / postfix / private / auth'
你在哪里告诉后缀与该套接字交谈？
