Postfix 不接收來自本地主機外部的郵件

我在我的 Parabola（基於 Arch）安裝中設置了 Postfix + Dovecot。看起來它可以工作，我可以向任何地址發送電子郵件並且它可以工作，並且還可以接收郵件**，但只能來自本地地址**。

如果我這樣做mail my@domain.org了，我會收到電子郵件（例如自動向我發送電子郵件）。但是，如果我從另一個電子郵件帳戶（外部帳戶）發送郵件，我根本就不會收到它。

所有埠都在本地工作，但如果我嘗試telnet [my_public_IP] 25（或 587）它會失敗（我會問我的 ISP 發生了什麼）。

更新：這是今天 8 月 24 日的日誌。它是 mail.log、mail.err 和 mail.info 的組合

感謝@Stefan的回答，但我也必須這樣做：

$ sudo postconf -e 'mydestination = localhost.$mydomain, localhost, $mydomain'

現在我可以收到來自外面的郵件了…

PS：我可以在“mydestination”中指定“all”嗎？

inet_interfaces = localhost # I've tried using my IP address, with no luck`

如果您只在 localhost 上收聽，您的 smtp 伺服器將無法從外部訪問。您可能應該將其更改為all。參看。 http://www.postfix.org/postconf.5.html#inet_interfaces

重新啟動後綴服務後，您可以檢查netstat -tulpn伺服器正在偵聽的介面和埠。

如果 postfix 正在偵聽埠 25 上的所有介面但仍無法從外部訪問，則應檢查防火牆設置
