如果我启用了电子邮件转发，我将无法接收任何电子邮件，但当我禁用电子邮件转发时。然后网络邮件工作正常。有人，请查看电子邮件日志？我看不到任何发送和接收问题。在cyberpanel上禁用电子邮件转发时。
此问题仅在启用电子邮件转发后才会出现。

这里有许多配置问题。导致拒绝的原因是：
command line usage error. Command output: lda: Fatal: Unknown argument: unix Usage: dovecot-lda [-c <config file>] [-d <username>] [-p <path>]
但也存在垃圾邮件杀手问题(找不到规则(和其他问题(/var/log/policyServerSocket丢失(。
这看起来不像是转发问题，而是一个普遍的错误配置问题。
在这里很难提供准确的建议，您应该与熟悉这些内容的人一起查看整个配置。
