使用bash更改sendmail發件人

Question

運行sendmail命令我通常會收到發件人的電子郵件，如username@hostname。

有沒有辦法使用sendmail發送電子郵件並將發件人設置爲與用於運行命令的用戶帳戶不同的內容？

什麼你要找的是-f：

sendmail -F "Your name" -f "your-address@example.com" < your-message.txt 

從sendmail man page：

-Ffullname Set the full name of the sender. 

-fname  Sets the name of the ``from'' person (i.e., the sender of the 
      mail). -f can only be used by ``trusted'' users (normally 
      root, daemon, and network) or if the person you are trying to 
      become is the same as the person you are.
