在Linux上快速发送本地邮件（linux 发送本地邮件）

Sending mail on a Linux system is a process that is surprisingly simple, but unfortunately some people do not take the time to understand the process. For this article, I will be demonstrating the process of sending an email from the command line, but it is also possible to do this through a graphical mail program.

一个Linux系统上发送邮件是一个惊人简单的过程，但不幸的是，有些人没有花时间去理解这个过程。在本文中，我将演示从命令行发送邮件的过程，但也可以通过图形邮件程序来实现。

The first step to sending a mail from the command line is to install a mail client. There are many programs available, including his, msmtp, and postfix. For this demonstration, I will be using sendmail. It can be installed through the package manager of most distributions.

从命令行发送邮件的第一步是安装一个邮件客户端。有很多可用的程序，包括his，msmtp和postfix。在本演示中，我将使用sendmail。它可以通过大多数发行版的包管理器安装。

Once sendmail is installed, you need to configure it to send emails. You will need to edit the sendmail configuration file, usually located at /etc/mail/sendmail.cf. You will need to set the SMTP(Simple Mail Transfer Protocol) server settings, such as the hostname, port number, authentication settings and encryption.

一旦sendmail安装完成，您需要配置它以发送邮件。您需要编辑sendmail配置文件，通常位于/etc/mail/sendmail.cf。您需要设置SMTP（简单邮件传输协议）服务器设置，例如主机名，端口号，认证设置和加密。

Once the configuration is complete, all that is left is to send the email. To do this, you simply need to use the ‘sendmail’ command followed by the desired recipient. For example, if you want to send an email to [email protected], you would type:

配置完成后，剩下的就是发送电子邮件了。要做到这一点，您只需要使用“ sendmail”命令，然后跟上期望的收件人。例如，如果您要发送一封电子邮件给[email protected]，您将键入：

sendmail [email protected]

When the command is run, you will be prompted to enter the email message. You can use the editor of your choice, or simply type the message directly into the command line. When you are finished, simply type `.` on a blank line to indicate the message is complete.

运行该命令后，您将被提示输入电子邮件正文。您可以使用自己喜欢的编辑器，或者只需在命令行中直接键入信息即可。完成后，只需在空白行中输入“.”以指示消息完成。

That’s all there is to it! Sending mail on Linux is a quick and easy process once you understand the basics. If you are having any trouble, make sure that your mail client is configured correctly and that you have verified the settings.

这就是全部！一旦您了解基础知识，在Linux上发送邮件就是一个快速，简单的过程。如果您遇到任何问题，请确保您的邮件客户端配置正确，并且您已验证过设置。
