bash - 使用 bash 更改 sendmail 发件人

Question

运行 sendmail 命令，我通常会收到发件人为 username@hostname 的电子邮件。

有没有办法使用 sendmail 发送电子邮件并将发件人设置为不同于用于运行命令的用户帐户？

你要找的是-f:

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

来自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.
