系统环境:rhel6 x86_64 selinux and iptables disabled 1.使用extmail自带模板在mysql中创建数据库 yum install mysql mysql-server mailx -y /etc/init.d/my
1.使用extmail自带模板在mysql中创建数据库
yum install mysql mysql-server mailx -y
/etc/init.d/mysqld start
mkdir /var/www/extsuite; cd /var/www/extsuite/
tar zxf extmail-1.2.tar.gz
tar zxf extman-1.1.tar.gz
mv extmail-1.2 extmail
mv extman-1.1 extman
cd extman/docs/
vi init.sql 修改root@extmail.org的密码
mysql < extmail.sql 导入extmail自带数据库
mysql < init.sql 导入extmail的测试账户
2.配置postfix支持虚拟域
cd /var/www/extsuite/extman/docs/
拷贝模板文件：
cp mysql_virtual_alias_maps.cf
mysql_virtual_domains_maps.cf mysql_virtual_mailbox_maps.cf
/etc/postfix/
useradd -u 600 vmail
postconf -e inet_interfaces=all
postconf -e virtual_mailbox_base=/home/vmail
postconf -e virtual_uid_maps=static:600
postconf -e virtual_gid_maps=static:600
postfix读取模板文件：
postconf -e
virtual_alias_maps=mysql:/etc/postfix/mysql_virtual_alias_maps.cf
postconf -e
virtual_mailbox_domains=mysql:/etc/postfix/mysql_virtual_domains_maps.cf
postconf -e
virtual_mailbox_maps=mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
重启postfix，查看是否成功！
/etc/init.d/postfix restart
echo "hello world" | mail -s test
support@exmail.org
[root@desktop19 dovecot]# cd
/home/vmail/
[root@desktop19 vmail]# ls
extmail.org
目录存在则postfix配置成功
3.配置MDA(dovecot)
yum install dovecot dovecot-mysql -y
cd /etc/dovecot/conf.d/
vi 10-mail.conf
mail_location = maildir:/home/vmail/%d/%n/Maildir
邮件收取配置，这里采用mairdir形式
first_valid_uid = 600
vim 10-auth.conf
!include
auth-sql.conf.ext 去掉注释
cd ../
vi dovecot-sql.conf.ext
driver
=mysql
connect
= host=localhost dbname=extmail user=extmail
password=extmail
default_pass_scheme = MD5
password_query =
SELECT username, domain, password
FROM mailbox WHERE username = '%u' and domain = '%d'
user_query =
SELECT maildir, 600 AS uid, 600 AS gid FROM mailbox WHERE username
= '%u'
启动dovecot,测试
/etc/init.d/dovecot start
***************************************************
[root@desktop19 Maildir]# telnet localhost 110

4.配置web界面：
vi /etc/httpd/conf/httpd.conf
*************************************************************
<VirtualHost *:80>
ServerName www.example.com
DocumentRoot /var/www/html
</VirtualHost>
<VirtualHost *:80>
ServerName mail.extmail.org
DocumentRoot
/var/www/extsuite/extmail/html/
ScriptAlias /extmail/cgi
/var/www/extsuite/extmail/cgi
Alias /extmail
/var/www/extsuite/extmail/html
ScriptAlias /extman/cgi
/var/www/extsuite/extman/cgi
Alias /extman
/var/www/extsuite/extman/html
SuexecUserGroup vmail vmail
</VirtualHost>
*************************************************************
cd /var/www/extsuite/extmail
chown vmail.vmail cgi/ -R
cp webmail.cf.default webmail.cf
vi webmail.cf
SYS_MAILDIR_BASE = /home/vmail
SYS_MYSQL_USER = extmail
SYS_MYSQL_PASS = extmail
SYS_CRYPT_TYPE = plain
cd /var/www/extsuite/extman
chown vmail.vmail cgi/ -R
cp webman.cf.default webman.cf
vi webman.cf
SYS_MAILDIR_BASE = /home/vmail
SYS_SESS_DIR = /tmp/
SYS_CAPTCHA_LEN = 4
SYS_CRYPT_TYPE = plain
启动httpd，测试界面：
如图2，
则安装CGI：yum install *CGI -y
如图3
则安装perl-ExtUtils-MakeMaker,gcc
tar zxf Unix-Syslog-1.1.tar.gz
cd Unix-Syslog-1.1
perl Makefile.PL
make test
make install
在新用户注册时，出现验证码显示不正常则：
如图4，
安装：yum install -y perl-GD
如图5
支持监控：
yum install rrdtool-perl -y
tar zxf File-Tail-0.99.3.tar.gz
cd File-Tail-0.99.3
perl Makefile.PL
make
make install
cp -r /var/www/extsuite/extman/addon/mailgraph_ext/ /usr/local/
/var/www/extsuite/extman/daemon/cmdserver -d
/usr/local/mailgraph_ext/mailgraph-init restart
5.反病毒配置：
yum install -y spamassassin -y
/etc/init.d/spamassassin start
下载病毒库管理软件：
clamav-0.97.6-1.el6.rf.x86_64.rpm
clamav-milter-0.97.6-1.el6.rf.x86_64.rpm
clamav-db-0.97.6-1.el6.rf.x86_64.rpm
clamd-0.97.6-1.el6.rf.x86_64.rpm
更新病毒库：
[root@desktop19 mnt]# freshclam

tar zxf MailScanner-4.84.5-3.rpm.tar.gz
cd MailScanner-4.84.5-3
./install.sh
配置MailScanner和postfix
vi /etc/MailScanner/MailScanner.conf
Run As User =
postfix
Run As Group =
postfix
Incoming Queue Dir
= /var/spool/postfix/hold
Outgoing Queue Dir
= /var/spool/postfix/incoming
MTA = postfix
Virus Scanners =
clamav
Always Include
Spamassassin report = yes
Use Spamassassin =
yes
SpamAssassin User
State Dir = /var/spool/MailScanner/spamassassin
mkdir
/var/spool/MailScanner/spamassassin
chown -R postfix.postfix
/var/spool/MailScanner/*
postconf -e
header_checks=regexp:/etc/postfix/header_checks
echo /^Received:/ HOLD >>
/etc/postfix/header_checks
测试：
信件携带病毒时，查看日志：tail -f /var/log/maillog
若信件正常，则显示已信任
