不确定我哪里做错了。
我已经配置了 postfix，以便它效果很好做的时候：
- 将电子邮件从外部来源中继/重定向到用户的虚拟邮箱（例如，他们的 Gmail 帐户）
- 将电子邮件从内部来源（例如，服务器警报）发送到外部邮箱（例如，我的个人电子邮件）
但它失败的正在做：
将内部来源的电子邮件（前面提到的服务器警报）发送到用户的虚拟邮箱。
我收到如下错误：
Jan 08 03:21:16 hermes postfix/qmgr[153]: CDBB11BC1A1F: from=<[email protected]>, size=1012, nrcpt=1 (queue active)
Jan 08 03:21:16 hermes postfix/virtual[5307]: CDB4C1BC165E: to=<[email protected]>, relay=virtual, delay=25790, delays=25790/0/0/0, dsn=4.3.5, status=deferred (mail system configuration error)
[email protected]通过虚拟表中继/重定向到我的个人邮箱。
关于我应该从哪里进行故障排除，有什么指示吗？
