RedHat8.0 Server Configuration Guide-Webmail implementation

Article Title: RedHat8.0 Server Configuration Guide-Webmail implementation. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
RedHat8.0 comes with a webmail written in php, which provides a mail web Interface Based on sendmail or postfix. The configuration method is also very simple. You only need to follow the steps below, you can easily build a Web mail server for yourself.
　　
Related Software:
First, if you do not select full installation, make sure that your system has at least the following RPM packages:
　　
1. php-4.2.2-8.0.5
　　
2. php-imap-4.2.2-8.0.5
　　
3. imap-2001a-15
　　
4. squirrelmail-1.2.7-4
　　
5. httpd-2.0.40-8
　　
Software Upgrade
Squirrelmail with RedHat8.0 has a security vulnerability. Therefore, use up2date to update to the squirrelmail-1.2.8-1, or directly access www.redhat.com to obtain the updated RPM package.
　　
# Rpm-Uvh squirrelmail-1.2.8-1.noarch.rpm
　　
Install or upgrade
　　
Configure httpd
Let's not talk about anything here. The configuration file definition ServerName must be modified for apache in the RPM package. Otherwise, an alert will be reported during startup and the server cannot be found. Add ServerName YOU_IP or Domain_Name to httpd. conf.
　　
Configure squirrelmail
After the squirrelmail RPM package is installed, all the page files are placed in the/usr/share/squirrelmail directory. We need to link it to the apache html directory for use, run the following command to create the link directory:
　　
# Ln-s/usr/share/squirrelmail // var/www/html/mail
　　
Note: cp replication won't work, because the paths of many squirrelmail files are relative paths. If you don't want to change the code yourself, you should make a solid link.
　　
Configure the default parameters of squirrelmail
The main configuration file is config. php. In the config directory of aquirrelmail, you can directly modify this file, or use the configuration script prepared by squirrel for us to easily customize parameters. this script is conf In the config directory. pl. Run this script with the perl interpreter installed in the system.
　　
#./Conf. pl
　　
SquirrelMail Configuration: Read: config. php (1.2.0)

Command>
　　
Enter the number of the menu to be customized after the prompt to modify the parameter or go to the next sub-menu. I mainly changed the following:
　　
Change 1. Organization Preferences --> 6. Default Language: zh_CN
　　
Change 2. Server Settings --> 1. Domain: localhost is your Domain name
　　
Change 4. General Options --> 1. Default Charset: gb2312
　　
7. message of the Day (MOTD) --> 1 Edit the MOTD select Edit the MOTD, You can Edit a paragraph, this section will be displayed in the webmail interface, the administrator can easily publish notifications and other information through MOTD.
　　
Change 8. plugins select all ins. Each ins you select will correspond to related functions in webmail Options, such as calendar, external pop3, filter, and spelling check. if you think some plug-ins are of little use to you, you can also remove them from the configuration file.
　　
Use webmail
Start the following services:
　　
#/Etc/init. d/httpd start
　　
#/Etc/init. d/sendmail start
　　
Modify disable in/etc/xinetd. d/imap to no and restart xinetd.
　　
#/Etc/init. d/xinetd restart
　　
Okay. Create an email test account:
　　
# Adduser-s/bin/false test
　　
# Passwd test
　　
Open your browser and enter the address of your email server, for example, http: // 192.168.0.253/mail.
　　
Enter the password of the account test and the account test in the input box to log on to the mailbox.
　　
Set the default encoding:
After logging on, you will find that the man in the sent email cannot be properly displayed and will become such a character as a test. Obviously, the encoding is incorrect, so we need to select the character set as Chinese in Options> Display Preferences --> Language, but here we only have the Big5 encoding of Taiwan. What should we do. you have to add code by yourself. the encoding-related file is i18n in the function directory. in php, you will find that the gb2312 encoding has been commented out and removed from the comment.
　　
/*---------------
　　
$ Ages ['zh _ cn'] ['name'] = 'China ';
　　
$ Ages ['zh _ cn'] ['charset'] = 'gb2312 ';
　　
$ Ages ['cn'] ['Alias'] = 'zh _ cn ';
　　
*/
　　
Then resend a Chinese email to check. OK
