我是网络管理员的新手，我遇到了 Squirrel Mail 无法接收邮件的问题，我发现某处说重新安装 doevcot 可以解决这个问题，所以我照做了，但现在我甚至无法登录 Squirrel Mail。
我正在使用 Ispconfig 3 运行 Centos 5.6。
以下是错误日志：

我尝试安装另一个邮件客户端“RoundCube”，删除并重新创建了邮件域和邮箱，但仍然没有任何效果。好像邮件客户端无法验证用户详细信息。
答案1
您的问题与 SquirrelMail 本身无关。SquirrelMail 只是一个 Web 前端，所有与邮件相关的“实际”错误都发生在 IMAP/SMTP 级别。从日志来看，我认为您的服务器没有saslauthd运行，或者 Postfix/Dovecot 设置中的服务器路径配置错误。
