Postfix 会退回收件人大写字母（未知用户）的来信

我刚刚在 Debian 最小服务器上安装了 Postfix，并进行如下配置：

安装：

  1. 安装它
  2. 选择internet site
  3. 将名称设置为mydomainname.com

/etc/postfix/main.cf配置：

  1. 变成myhostname​mydomainname.com
  2. 更改alias_maps为virtual_alias_maps并将其设置为hash:/etc/postfix/virtual

/etc/postfix/virtual内容：

（Shahab@eeePC 是我的本地用户首字母大写！！）

  1. 添加条目[email protected] Shahab
  2. 跑了sudo postmap /etc/postfix/virtual
  3. 跑了sudo service postfix restart

我从 gamil 发送了一封电子邮件至[email protected]，以下是其记录/var/log/mail.log：

问题是 Postfix 无法识别我的用户或其他东西并删除了邮件。
