我正在configuration一个全新的postfix / dovecot服务器，但是我的脑细胞正在融化，我无法注意如何做到这一点。 所有的工作，后缀已启用启动（我看到它在雷鸟configuration），但dovecot不。 我尝试将disable_plaintext_auth更改为yes ，Thunderbird告诉我必须将身份validation方法更改为STARTTLS但是当我再也无法执行任何操作时。
我没有任何错误，但无法接收或发送电子邮件（电子邮件正确发送，但不复制到发送的文件夹）。
在日志中，我每次尝试访问Thunderbird文件夹时都会看到这一点
mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>
我认为这只是一个正常的variables，但我找不到它。
