CentOS/Nginx/SendMail/Dovecat/Perl/OpenWebMail <构架邮件服务器>

  1. 安装Sendmail
    yum安装或者rpm包安装:
    yum -y install sendmail sendmail-devel sendmail-cf sendmail-do m4
  2. 设置在系统35级别启动
    #chkconfig –level 35 sendmail on
    #chkconfig –list sendmail
    sendmail        0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭
  3. #vim /etc/mail/local-host-names  //添加邮件服务器的邮件服务域名
    xxx.com
  4. 开启sendmail服务器的网络接口
    #cp sendmail.mc sendmail.mc.bak   为了防止出错,备份配置文件
    #vim /etc/mail/sendmail.mc
    查 找:DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1,’)dnl
    修改为:DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0,’)dnl
  5. 设置SMTP的用户认证
    #vim /etc/mail/sendmail.mc
    查找:dnl 52 TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN’)dnl
          dnl 53 define(`confAUTH_MECHANISMS’, `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN’)dnl
    去掉前面注释:“dnl”
    在sendmail服务器中使用了saslauthd服务程序提供用户认证功能,所以要开启它
    #chkconfig –level 35 saslauthd on
    #service saslauthd start
  6. 生成sendmail.cf文件
    #cd /etc/mail
    #m4 sendmail.mc > sendmail.cf
    #service sendmail restart
  7. 用户管理
    #groupadd mailuser   建立邮件用户组
    #useradd -g mailuser -s /sbin/nologin mike   建立不能登录系统的邮件用户
    #vim /etc/aliases   sendmail使用aliases机制实现邮件别名和群发功能
    admin:           mike                     admin是mike的别名
    testgroup:            mike,john,tom,jack                    邮件群发,向testgroup邮箱发送就是向4个人发送
    # newaliases    对aliases.db数据库更新
  8. 安装POP3,IMAP功能
    #yum install dovecot
    #vim /etc/dovecot.conf
    查 找:protocols = imap imaps
    修改为:protocols = imap imaps pop3 pop3s
    #chkconfig –level 35 dovecot on
    #service dovecot restart
  9. 安装openwebmail
    下载所需软件包:www.openwebmail.org   www.rpmfind.net
    yum install perl-CGI-SpeedyCGI perl-suidperl perl-Compress-Zlib perl-Text-Iconv
    rpm –ivh –nodeps openwebmail-data-2.53-3.i386.rpm
    rpm –ivh –nodeps openwebmail-2.53-3.i386.rpm

10. 初始化openwebmail系统
#/var/www/cgi-bin/openwebmail/openwebmail-tool.pl –init

11. 修改配置文件
#vim /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
domainnames                                   xxx.com
default_language                      zh_CN.GB2312
default_iconset                 Cool3D.Chinese.Simplified

12. 安装PerlFastCGI模块
FCGI: http://cpan.wenzk.com/authors/id/F/FL/FLORA/FCGI-0.71.tar.gz
#tar zxvf FCGI-0.71.tar.gz
#cd FCGI-0.71
#perl Makefile.PL
#make && make install
#rpm -ivh perl-FCGI-ProcManager-0.18-1.el4.rf.noarch.rpm
或者:yum install perl-FCGI-ProcManager

13. 配置PerlFastCGI脚本(perl-fast
上传脚本文件到:/etc/init.d/   目录下
#chmod +x  /etc/init.d/perl-fast
#vim /etc/profile
添加以下内容:
export FCGI_SOCKET_PATH=”/tmp/perl-fastcgi.sock”
export FCGI_NPROCESSES=4
#source /etc/profile
#/etc/init.d/perl-fast &

14. 上传enable_perl.conf文件到:nginx/conf  目录下,然后为Nginx添加FastCGIPerl支持
server
{
       listen 80;
       server_name mail.xxx.com;
       charset gb2312;
       access_log /wslogs/xxx.com/mail_access.log combined;
       error_page 404 = http://www.xxx.com/error/404.html;
       error_page 500 502 503 504 = http://www.xxx.com/error/50x.html;
       location /
       {
                root /var/www;
                index index.html index.htm index.php;
       }
       location ~* .*\.pl$
       {
                root /var/www;
                include enable_perl.conf;
        }
}

15. web服务器中发布openwebmail
为了浏览器中不用输入很长的地址,做一个引导页
#vim /var/www/index.php
<script>
location.href=”cgi-bin/openwebmail/openwebmail.pl”;
</script>

16. 文件权限的设置
#chown root.root /var/www/cgi-bin/openwebmail/
#chown root.mail /var/www/cgi-bin/openwebmail/*
#chmod 775 /var/www/cgi-bin/openwebmail/openwebmail*.pl
#chown root.mail /var/www/cgi-bin/openwebmail/openwebmail*.pl
#chmod 4555 /usr/bin/suidperl
#chmod 775 /var/www/cgi-bin/openwebmail/etc/sessions
