Blueonyx 5.x 安装 OpenWebmail

By | 2018-11-26
其实安装方法很简单,但确实花了小弟不少时间,以下是详细过程:

平台:  Blueonyx 5.6 + OpenWebmail 2.5.1

下载最新版本的 BlueOnyx , 这套系统还是免费的,前身就是大名鼎鼎的 Sun Cobalt ,当时开发出来是给 ICP 作为 Web host用,系统包括Email Server(SMTP/POP3/IMAP)、FTP Server 、DNS Server、Web Server 全部包括,最适用于ICP主机出租业务了; 介绍就到这里,继续安装。

  • 安装OpenWebmail

Blueonyx 的安装就不再说明了,因为就是光盘安装的很简单,只要稍懂英文真的没有什么难度了! 系统是“定制”版本的 CentOS5 ,所以安装软件与CentOS安装没有什么区别,简单点就是取得“软件源库” repo 文件,然后 yum install xxxxxx 即可,跟”大便“的 apt-get 一样很给力的
其实系统自带有 webmail 了,就是SquirrelMail , 但小弟用了Openwebmail快10年了,感觉很顺手,界面也很友好,功能也全部好用,所以先入为主吧,还是需要在这个系统上使用,所以才post该文!

下文内容参考自: http://coding.infoconex.com/page/Installing-OpenWebmail-on-BlueOnyx-server.aspx

1) Grab the latest install of openwebmail from: http://openwebmail.acatysmoof.com/

2) 下载 openwebmail文件包到 /var/www

3) 解压文件包

  • tar -xvzf openwebmail-2.53.tar.gz
  • This will extract files to 2 different directories
    • /var/www/cgi-bin/openwebmail
    • /var/www/data/openwebmail

4) 更改目录权限为 root:mail

  • chown root:mail /var/www/cgi-bin/openwebmail
  • chown root:mail /var/www/data/openwebmail

5) 安装Text::Iconv perl模块

  • yum install perl-Text-Iconv

    或者直接下载rpm包安装

  • http://openwebmail.org/openwebmail/download/redhat/rpm/packages/centos5/
    下载 perl-Text-Iconv/ 的rpm包到 Blueonyx 中,然后执行
    # rpm -i perl-Text-Iconv.xx.xxx.rpm

6) 新建apache配置文件

  • 新建 /etc/httpd/conf.d/httpd_openwebmail.conf
  • 贴上以下内容或者直接下载该文件: http_openwebmail.conf

 

### Begin – Added for openwebmail ###

ScriptAlias /webmail “/var/www/cgi-bin/openwebmail/openwebmail.pl”
ScriptAlias /openwebmail “/var/www/cgi-bin/openwebmail/”
Alias /data “/var/www/data”

<Directory /var/www/cgi-bin/openwebmail>
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all
AddHandler cgi-script .cgi .pl
</Directory>

ExpiresByType image/gif A86400
ExpiresByType image/png A86400
ExpiresByType image/jpg A86400

</Directory>

###  End  ###

7) 修改两个openwebmail.conf文件的参数

  • vi /var/www/cgi-bin/openwebmail/etc/openwebmail.conf
    再者就是
    vi /var/www/cgi-bin/openwebmail/etc/default/openwebmail.conf
    两个文件里的对应参数都必须按以下修改
    • auth_module                   auth_pam_cobalt.pl
    • ow_cgidir                         /var/www/cgi-bin/openwebmail
    • ow_cgiurl                         /openwebmail
    • ow_htmldir                       /var/www/data/openwebmail
    • ow_htmlurl                       /data/openwebmail

      这里的 auth_pam_cobalt.pl 里 Sun Cobalt 公司专用的验证程序

  • Here is a complete example file that is from my system that reflects not only the above changes but other changes I make from the default to support our current user preferences.
  • openwebmail.conf
    • Note if you enable spell check like my above example configuration make sure you install the aspell library
    • yum install aspell
  • You should open /var/www/cgi-bin/openwebmail/etc/openwebmail.conf.help if you want to understand all the possible settings that can be made
    以上是openwebmail.conf的配置说明,大家可以从网上找到很多关于openwebmail默认配置实例,这里就不再重申了!

8) 修改 db.conf

  • nano -w /var/www/cgi-bin/openwebmail/etc/defaults/dbm.conf
  • 修改为以下内容
    dbm_ext                       .db
    dbmopen_ext               .db
    dbmopen_haslock        no

9) 重启 httpd 服务

  • /etc/init.d/httpd restart

10) 执行以下命令

  • /var/www/cgi-bin/openwebmail/openwebmail-tool.pl –init

      11) 完成全部安装及配置过程

  • http://server_ip_address/webmail

多域名時用戶跟隨域名:
openwebmail.conf 裡增加參數,寄件人地址會跟隨訪問OPENWEBMAIL使用的域名

domainoverride     yes
——————-

增加用户邮箱 quota 功能

# vi /var/www/cgi-bin/openwebmail/etc/openwebmail.conf

在文件最后加入以下代码,即限制用户邮箱空间为60M
############################################
# Quota System (limit in KB and threshold in %)
1 MB =     1,024 KB
10 MB =    10,240 KB
100 MB =   102,400 KB
1 GB = 1,024 MB = 1,048,576 KB
# uncomment following lines if you wish to enable Quota System for 10 Mb

quota_module            quota_du.pl    <– 如果使用 quota_unixfs.pl 將會跟隨系統對每個用戶的限額
spool_limit             61440
quota_limit             61440
quota_threshold         0
delmail_ifquotahit      yes
delfile_ifquotahit      yes

如果使用CentOS 平台 openwebmail 使用 auth_unix.pl 的验证模式,需要修改openwebmail.conf

# vi /var/www/cgi-bin/openwebmail/etc/defaults/auth_unix.conf

a. set passwdfile_encrypted to ‘/etc/shadow’

b. set passwdmkdb           to ‘none’

不然用户使用openwebmail无法登录
