postfix+dovecot+extmail+spamassassin+MailScanne...

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/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[email protected]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 [email protected]
     [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

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
ClamAV update process started at Tue Mar  5 15:35:12 2013

   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
