我正在尝试更改我的sendmail配置，以便将所有“用户未知”电子邮件发送到特定帐户（baduser）。 我将DL定义添加到sendmail.mc并生成了test.cf. 然后我使用以下方法测试了这个新配置：
回复谁| sendmail -v -Ctest.cf noone并且电子邮件已正确发送到定义的帐户。
然后我将test.cf重命名为sendmail.cf（在/ etc / mail中）并重新测试：
回复什么| sendmail -Csendmail.cf noone
再次将电子邮件发送到baduser帐户。
对此感到高兴，然后我重新启动了sendmail（通过systemctl）并再次向无效帐户发送了一封电子邮件。
我收到了550 5.1.1用户未知的拒绝电子邮件，而不是将电子邮件发送给恶意用户。
我在这里错过了什么。
（Fedora 22＆amp; sendmail 8.14.7 / 8.13.3）
