我只是为了好玩和学习而设置这个网络服务器，所以如果没有人知道我的问题是什么，那没关系。

我已经搜索了 stackoverflow/google 并没有找到任何解决方案。

我能够登录到我在松鼠邮件中创建的测试用户，但无法发送/接收电子邮件。

在错误日志中：

Jun 17 03:52:34 vps46420 postfix/smtpd[2490]: connect from localhost[127.0.0.1]

显然，由于 Unix 套接字文件不是由 Dovecot 创建的，进程smtpd无法启动。auth通过运行确认：

$ sudo ls -l /var/spool/postfix/private/auth

它应该输出“没有这样的文件或目录”。

尝试将此行附加auth_mechanisms = plain login到dovecot.confThen Restart Dovecot 中，然后再次检查套接字。

$ sudo service dovecot restart

您还需要确认 Dovecot 在 Debian 8 上正在运行：

$ sudo tail /var/log/syslog

或检查端口 143 和/或 993 是否通过以下方式打开：

$ sudo netstat -plnt

如果端口不存在，请将以下行添加到dovecot.conf：

service imap-login {
  inet_listener imap {
    port = 143
  }
  inet_listener imaps {
    port = 993
  }
}

我建议阅读我的博客文章以设置简单且安全的邮件服务器。
