Cause: It is faster than php, so I used it for a long time on the Internet. I didn't know how to set up extmail on Ubuntu. I tried it myself. It's almost a month and I finally got it done, it has been tested for a week, and there is not much problem. Now let's share it with you.

Let's not talk much about it. Start:

The following describes the extmail Mail System Architecture in Ubuntu 9.04, which can be referenced in Ubuntu 9.10.

Software environment:

Function module content remarks

Install LAMP on Web Server

Most of the above software can find extmail, extman, and spam loocker on the Ubuntu source. You can download the latest version at http://www.extmail.org/cgi-bin/download.cgi.

First, install the system, host name mail.extmail.org, language, upgrade the system, and use the root permission to log on to the system. After all the steps are completed, we can run it on the terminal.

Sudo tasksel

The interface is the same as the new one. Here I select "LAMP Server", "OpenSSH Server", and "Samba fileserver". You can choose one as required, move the cursor to the software you want to install and press "space" to select. During installation, you will be asked to enter the "Mysql" password. After installation, we also need to install phpmyadmin to manage mysql.

Sudo apt-get install phpmyadmin

When "phpmyadmin" is installed, "Configure database for phpmyadmin withdbconfig-common?" appears ?", Select "no". Open "Firefox" and enter "localhost/phpmyadmin" in the address. The phpmyadmin interface indicates that you have succeeded.

In the previous step, I installed the "openssh server" Remote Management Service. I configured "Log on based on RSA key", which is more secure.

Sudo ssh-keygen-t rsa

Generate public/private RSA key pairs.
Enter the file with the key (/home/B/. ssh/id_rsa ):
Enter passphrase (empty for no passphrase ):
Enter the same passphrase again:
Your verification file is saved in/home/B/. ssh/id_rsa.
Your public key is stored in/home/B/. ssh/id_rsa.pub.
