SquirrelMail 不發送或接收任何郵件

我只是試圖在我的 Ubutnu 14.04 上設置一個郵件伺服器。目標是能夠從 info@mydomain.com 發送郵件並接收發送到同一地址的郵件。

現在我按照本教程安裝 Postfix、Dovecot 和 SquirrelMail。我按照教程進行操作，一切正常。此外，我將我的info-user 添加到郵件組，並且我設置了從 @ 到 @ 的 MX 記錄，因此作為主機，所有內容都發送到我的域。我發現這是其他人的一個問題，它為他解決了這個問題。對我來說，它並沒有改變任何東西。

現在 SquirrelMail 的 web 部分工作正常，我可以到處點擊並撰寫郵件。已發送的郵件也在 SENT-Folder 中。

但是，我既沒有在 SquirrelMail 上接收郵件，也沒有在我嘗試從 SquirrelMail 發送郵件的郵件帳戶上接收郵件。我嘗試了 1and1、web.de 和 gmail ……都沒有結果……

我檢查了var/log/mail.err沒有結果。

但是：在 中mail.log，有一些有趣的行，我只是將它們粘貼到這裡：

請注意，我用偽地址替換了真實地址。

老實說，我真的不知道這些錯誤，但我認為像NOQUE: reject,Relay access denied或status=deferred (host mx-ha02.web.de[212.227.17.8] refused to talk to me:看起來不太好。

有人知道我缺少什麼或應該解決什麼嗎？

您也可以檢查我對域 chatXpress.com 的設置，因為info@chatxpress.com來自 centralops 的域檔案返回

謝謝你的幫助！

您在這裡（至少）有兩個不同的問題：

首先，您無法接收帶有錯誤的郵件Relay access denied。這意味著 Postfix 未配置為接收您的域名的郵件。

要解決這個問題，您需要重新配置 Postfix，例如使用dpkg-reconfigure postfix並給它正確的域名。似乎 Postfix 是使用名稱localhost.localdomain而不是chatxpress.com.

其次，您無法發送郵件，因為根據您收到的錯誤消息，您的主機的 IP 地址沒有 PTR 記錄。我能夠證實這一點：

$ host 85.93.24.159
Host 159.24.93.85.in-addr.arpa. not found: 3(NXDOMAIN)

PTR 記錄必須由 IP 地址的所有者設置，即託管您的伺服器的數據中心。聯繫他們以獲取有關如何設置 PTR 記錄的更多資訊。
