Four steps to teach you how to build a small mail server

A multi-enterprise LAN has a mail server for document delivery and work communication. But the use of professional enterprise mail system software requires a lot of capital investment, which is unbearable for many companies. In fact, we can set up a small mail server to meet our needs through the POP3 service and SMTP service provided by Windows Server 2003.

First, install POP3 and SMTP service components

Windows Server 2003 does not install POP3 and SMTP service components by default, so we have to add them manually.

1. Install the POP3 Service Component

Log in to the Windows Server 2003 system as a system administrator. Go to “Control Panel → Add or Remove Programs & Rarr; Add/Remove Windows Components", in the pop-up "Windows Components Wizard" dialog box, select the "Email Service" option, click “Details The ” button, you can see that this option includes two parts: POP3 service and POP3 service web management. In order to facilitate the user to manage the mail server remotely, it is recommended to select “POP3 Service Web Management”.

2.Install the SMTP Service Component

Select the “Application Server” option and click “Details” button, then view the details in the "Internet Information Services (IIS)" option, select the "SMTP Service" option, and finally click the <;OK” button. In addition, if users need remote web management of the mail server, be sure to select the "Remote Management (HTML)" component in the "World Wide Web Service". After completing the above settings, click the “Next” button and the system will start to install and configure POP3 and SMTP services.

Second, configure POP3 server

1. Create mail domain

Click “ Start → Management Tools & Rarr; POP3 Service & rdquo;, pop up POP3 service console window. After selecting the POP3 service in the left column, click the “new domain” in the right column to bring up the “Add Domain” dialog box, and then enter the domain name of the mail server in the “Domain Name” field, which is the email address. “@”The following sections, such as “rtj.net”, last click on the “OK” button. Where “rtj.net” is the domain name registered on the Internet, and the domain name is set in the DNS server MX mail exchange record, resolved to the Windows Server 2003 mail server IP address.

2.Create a user mailbox

Select the newly created “rtj.net” domain, click “Add Mailbox in the right column, pop-up Add Mailbox dialog box, in “ Enter the mail user name in the mailbox name & rdquo;, then set the user password, and finally click the “OK” button to complete the mailbox creation.

Third, configure the SMTP server

After completing the configuration of the POP3 server, you can start to configure the SMTP server. Click “Start → Programs & Rarr; Management Tools & Rarr; Internet Information Services (IIS) Manager & rdquo;, in the "IIS Manager" window right click on the "Default SMTP virtual server" option, in the pop-up menu Select "Properties" to enter the "Default SMTP Virtual Server" window, switch to the "General" tab, and select the IP address of the mail server in the "IP Address" drop-down list box. Click the “OK" button so that a simple mail server is set up.

After completing the above settings, the user can use the mail client software to connect to the mail server to send and receive mail. When setting the SMTP and POP3 server addresses of the mail client software, enter the domain name of the mail server “rtj.net”

4. Remote Web Management

Windows Server 2003 also supports remote web management for mail servers. In the remote client, run IE browser and enter “https://server IP address:8098” in the address bar. The connection dialog box will pop up, enter the administrator username and password, click “OK” Click the button to log in to the web management interface.
