理解 sendmail -bt 与别名的结合

我熟悉 exim 以及 exim -bt 在指示如何路由消息方面的行为。我正在尝试设置一个简单的 sendmail 配置，以将本地系统上的根邮件路由到我的公司电子邮件地址。

# tail /etc/aliases

# Person who should get root's mail
root:       [email protected]

运行后newaliases，目前正常工作但我不明白如何使用 -bt 在本地进行验证。

# sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> /try smtp root
Trying envelope recipient address root for mailer smtp
canonify           input: root
Canonify2          input: root
Canonify2        returns: root
canonify         returns: root
2                  input: root
2                returns: root
EnvToSMTP          input: root
PseudoToReal       input: root
PseudoToReal     returns: root
MasqSMTP           input: root
MasqSMTP         returns: root < @ *LOCAL* >
EnvToSMTP        returns: root < @ olympus . domain . >
final              input: root < @ olympus . domain . >
final            returns: root @ olympus . domain
Rcode = 0, addr = [email protected]
> 3 root
canonify           input: root
Canonify2          input: root
Canonify2        returns: root
canonify         returns: root
> /try local root
Trying envelope recipient address root for mailer local
canonify           input: root
Canonify2          input: root
Canonify2        returns: root
canonify         returns: root
2                  input: root
2                returns: root
EnvToL             input: root
EnvToL           returns: root
final              input: root
final            returns: root
Rcode = 0, addr = root

我应该输入以 开头root并输出的什么[email protected]？

答案1

尝试一下sendmail -bv root。
它应该显示 sendmail 如何将消息传递给给定的收件人。

man sendmail：

   -bv    Verify  names only - do not try to collect or deliver a message.
          Verify mode is normally used for  validating  users  or  mailing
          lists.

如果您还想查看内部规则集的处理，请将-d21.12调试开关添加到-bv。
