1.配置mysql

[root@server86
~]# yum install mysql-server -y

[root@server86
~]# vim /etc/hosts

192.168.122.186
server86.example.com

[root@server86
~]#
/etc/init.d/mysqld start

[root@server86
~]# chkconfig mysqld on

[root@server86
~]# mkdir -p /var/www/extsuite

[root@server86
kernel]# tar zxf extmail-1.2.tar.gz -C /var/www/extsuite/

[root@server86
kernel]# tar zxf extman-1.1.tar.gz -C /var/www/extsuite/

[root@server86
kernel]# cd /var/www/extsuite/

[root@server86
extsuite]# mv extmail-1.2/ extmail

[root@server86
extsuite]# mv extman-1.1/ extman

[root@server86
extsuite]# cd /var/www/extsuite/extman/docs/

[root@server86
docs]# mysql < extmail.sql (导入extmail自带数据库)

[root@server86
docs]# mysql < init.sql (导入extmail测试用户)

至此mysql配置完毕！！！

2.配置postfix

[root@server86
~]# yum install postfix -y

[root@server86
~]# /etc/init.d/postfix start

[root@server86
~]# chkconfig postfix on

[root@server86
~]# useradd -u 600 -s /sbin/nologin vmail

[root@server86
~]# cp /var/www/extsuite/extman/docs/mysql_virtual_alias_maps.cf
/var/www/extsuite/extman/docs/mysql_virtual_domains_maps.cf
/var/www/extsuite/extman/docs/mysql_virtual_mailbox_maps.cf
/etc/postfix/

[root@server86
~]# postconf -e inet_interfaces=all

[root@server86
~]# postconf -e virtual_mailbox_base=/home/vmail/

[root@server86
~]# postconf -e virtual_uid_maps=static:600

[root@server86
~]# postconf -e virtual_gid_maps=static:600

[root@server86
~]# postconf -e
virtual_alias_maps=mysql:/etc/postfix/mysql_virtual_alias_maps.cf

[root@server86
~]# postconf -e
virtual_mailbox_domains=mysql:/etc/postfix/mysql_virtual_domains_maps.cf

[root@server86
~]# postconf -e
virtual_mailbox_maps=mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf

[root@server86
~]# /etc/init.d/postfix restart

[root@server86
new]# mail postmaster@extmail.org

若配置成功会在/home/vmail/下建立extmail.org/postmaster/Maildir/目录，邮件存放在/Maildir/new/中。

至此postfix配置完毕！！！

3.配置extmail(前台)

[root@server86
~]# yum install httpd -y

[root@server86
~]# cd /var/www/extsuite/extmail/

[root@server86

1.安装反垃圾软件

[root@server86
~]# yum install spamassassin -y

[root@server86
~]# /etc/init.d/spamassassin start

2.安装反病毒软件

[root@server86
kernel]# yum localinstall clamav-0.97.6-1.el6.rf.x86_64.rpm
clamav-db-0.97.6-1.el6.rf.x86_64.rpm
clamav-milter-0.97.6-1.el6.rf.x86_64.rpm
clamd-0.97.6-1.el6.rf.x86_64.rpm
sendmail-milter-8.14.4-8.el6.x86_64.rpm -y

[root@server86
kernel]# /etc/init.d/clamd start

[root@server86
kernel]# /etc/init.d/clamav-milter start

[root@server86
kernel]# freshclam (更新病毒库)

注：通过执行rpm
-ql
clamav-db可以查看到病毒库在/var/clamav/下，并且更新病毒库后，会自动在/etc/cron.daily/中生成一个名为freshclam的日计划执行文件，每天自动更新一次病毒库

到www.eicar.org下载病毒eicar.com或者eicar.com.txt,用clamscan或clamdscan测试是否能扫描到病毒

安装并配置MailScanner

[root@server86
kernel]# tar zxf MailScanner-4.84.5-3.rpm.tar.gz

[root@server86
kernel]# cd MailScanner-4.84.5-3

[root@server86
MailScanner-4.84.5-3]# ./install.sh

会出现如下错误：

(1)You
need to install the patch command from your Linux distribution.

Once
you have done that, please try running this script again.

解决方法如下：

[root@server86
MailScanner-4.84.5-3]# yum install patch -y

(2)./install.sh:

then
install it first and come back and try again.

解决方法如下：

[root@server86
MailScanner-4.84.5-3]# yum install rpm-build -y

[root@server86
MailScanner-4.84.5-3]# /etc/init.d/postfix stop

[root@server86
