在 ubuntu 系統上，我安裝了 postfix 並在 /etc/postfix/main.cf 設定檔中設定了 relayhost 和 mynetworks 。
我現在可以遠端登入該伺服器上的連接埠 25，並透過發出 SMTP 命令發送電子郵件。我對 Gmail 帳戶進行了測試，並正常收到了電子郵件。
但在同一台 Linux 主機上，我安裝了郵件（apt-get mailutils）並執行了以下命令：
mail -s "test email" myname@gmailcom
輸入了一些訊息文字和 Ctrl-D，沒有看到任何錯誤，但收件人從未收到訊息。
我是否必須以某種方式在郵件配置中設定 smtp 伺服器？我應該看到某種隊列中等待發送的訊息嗎？
有關如何解決的任何提示嗎？
更多資訊：
我的 /etc/mailname 設定檔包含字串：mail.mydomain.com 且我的 Linux 機器沒有設定域（它只是一個測試系統）。我應該將其更改為僅郵件嗎？ （郵件是盒子的主機名稱）。
我找到了一種郵件語法，它允許您指定適合我的寄件者：
mail -s "message 5" -a "From: [email protected]" [email protected]
但我更願意修復，所以我不需要這樣做。
這是我透過互動使用郵件看到的錯誤：

若要查看郵件是否可能位於佇列中，請mailq在命令列上使用，或檢查目錄的內容/var/spool/mail。 Postfix 也應該記錄到- 您可以打開另一個 shell 會話，並在其他 shell 會話中/var/log/maillog運行時尾隨此文件- 使用mailtail -f /var/log/maillog
