linux - postfix配置方式下内部服务器选择什么类型的邮件配置

Question

我正在重新配置 postfix 以使 cron 作业能够向用户发送自动电子邮件通知。喜欢

$ sudo dpkg-reconfigure postfix

I got the following traceback:-
debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend requires a screen at least 13 lines tall and 31 columns wide.)
debconf: falling back to frontend: Readline

The "mail name" is the domain name used to "qualify" _ALL_ mail addresses without a domain name. This includes mail to and from <root>: please do not make
your machine send out mail from root@example.org unless root@example.org has told you to.

This name will also be used by other programs. It should be the single, fully qualified domain name (FQDN).

Thus, if a mail address on the local host is foo@example.org, the correct value for this option would be example.org.

System mail name: 

在上面我随机选择了 5.local 主机选项，它询问邮件名称，我不太确定邮件名称。谁能建议一种查找邮件名称的方法。

Answer 1

系统不会要求您查找邮件名称 - 系统会要求您分配邮件名称。此外 - 仅限本地邮件，因此只有在该服务器上拥有帐户的用户才能收到邮件。如果您打算将其发送到您的服务器之外(如 gmail)，您必须将其设置为 Internet 站点。
