Ubuntu
我無法從其他位置登錄到 IMAP/POP3
[標記為重複之前請閱讀]
我已經安裝
Postfix並dovecot打開Ubuntu（對於虛擬使用者）。所以我可以使用手機（郵件應用程序）甚至在 Windows（Windows Mail）上從家裡登錄郵件伺服器。
但是當我移動到不同的位置時，我無法再登錄了。
所以我嘗試更改
mynetwork為0.0.0.0in/etc/postfix/main.cf並沒有幫助：#mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mynetworks = 0.0.0.0我該如何解決這個問題？

我跟著這個教程：linuxize

最後它的工作。只需打開埠。對不起我造成的所有頭痛..
這可能是您的路由器的問題。您需要將 IMAP 和 POP3 埠轉發到您的伺服器。我建議您需要 TLS 並轉發 IMAPS 和 POP3S 埠。LetsEncrypt 項目允許您獲得受信任的證書，儘管對於小型網路，自簽名證書也可以使用。
您可能需要為您的家庭配置一個 DDNS（動態 DNS）名稱，以便您可以遠端連接。這將是一個不同於您在家裡的名字。這可以通過在本地 DNS 伺服器（例如 Dnsmasq）中設置自定義記錄來解決。
