Dovecot + Postfix 可以發送但電子郵件不會顯示在收件箱中
我正在嘗試在我的個人網站伺服器上設置電子郵件伺服器。我大部分時間都在那裡，我可以發送電子郵件，但向我設置的地址發送電子郵件似乎沒有用新文件填充
curornew目錄中的Inboxor目錄。Junk雖然Sent在發送電子郵件後會填充（這似乎總是成功）。相關軟體包的守護程序處於活動狀態，似乎沒有任何警告/錯誤。MX 記錄等似乎沒問題，DKIM 測試說一切都很好，而且我不在任何垃圾郵件列表中。在這一點上，我基本上迷路了。
我在具有以下軟體包版本的個人伺服器上使用 Arch Linux：
postfix 3.5.6-1 dovecot 2.3.10.1-2 opendkim 2.10.3-7 pigeonhole 0.5.10-2 procmail 3.22-10 spamassassin 3.4.4-3這是系統日誌的一部分（我認為不允許 postfix 擁有自己的日誌？）。這是唯一似乎有有價值資訊的部分，雖然我不明白。某種 milter 問題？（我也替換了個人辨識資訊，例如 IP 和域名）

Postfix 尚未配置為接受您的域名的郵件，因此當它查找域的 MX 記錄並發現它將自己指定為要發送到的郵件伺服器時，它會拋出錯誤“郵件循環回我自己”。因為它實際上並不接受您域的郵件，所以它唯一能做的就是退回郵件。
然後我們看到退回郵件本身也出於同樣的原因被退回。然後發生的事情是在您沒有發布的後續日誌條目中，但通常這樣的消息會被丟棄或記錄在某處。
您需要配置 Postfix 以接受您的域名的郵件。這需要設置 obth 中的
myorigin=指令main.cf，該指令應設置為$mydomain和該mydestination=指令，該指令應包括本地目的地郵件的多個值：myorigin = $mydomain mydestination = $myhostname, localhost.$mydomain $mydomain
