SMTP(後綴)和 iPhone - 無法發送電子郵件 - 拒絕:RCPT
我已經嘗試設置電子郵件伺服器 2 天,當我在 PC 上使用 roundcube 時一切正常,我可以發送和接收電子郵件,但是當我想在 iPhone 上設置我的電子郵件時問題開始了。我可以接收電子郵件,但不能發送任何電子郵件。

我在帶有 SSL/TLS、postfix+debian 的 ubuntu 上執行它。Postfix 沒有身份驗證。這是我的 main.cf:

您可能在伺服器上使用 Roundcube,預設情況下 localhost 被授權發送郵件。您的 iPhone 來自外部 IP,並且隨著時間的推移它可能會定期更改 IP,因此您不能簡單地授權該 IP 發送郵件。您需要使用登錄名/密碼對 postfix 進行身份驗證,才能被授權發送郵件,就像您向 dovecot 進行身份驗證以被授權閱讀您的郵件一樣。
Postfix 似乎已經設置為允許這樣做(smtpd_recipient_restrictions = permit_sasl_authenticated),但是您是否將 iPhone 配置為在發送郵件時使用相同的登錄名/密碼進行連接,因為它用於閱讀郵件?如果您還沒有這樣做,您可能還想告訴它連接到送出埠 (587) 而不是 smtp 埠 (25)。
