我正在尝试为我的 LAN 设置 Postfix 中继系统。我的许多服务都被 WAN 访问阻止,我希望能够从它们那里获取通知。
就目前情况而言,它目前“有效”,但每封电子邮件都附有“Mailer Deamon Undeliverable”电子邮件,因为它发送正确,但总是尝试密件抄送:[email protected]
这无法解决。我仅使用@domain.com 发送电子邮件。
这是我的“来宾”虚拟机的配置(通过发送relayhost
),我已经尝试了很多,但我没有任何想法,感谢任何帮助。
我想知道我是否可以在relayhost
与客人的比赛中以某种方式解决这个问题?

答案1
我有一个问题mydestination
。我不应该domain.com
在那个领域。我将其删除并将其设置为mydestination = hostname hostname.domain.com localhost
,现在它按预期工作。
