Installing Open WebMail v2.51. Assumes you already had v2.40 installed from the Nuonce PKG, etc.

这里要求原本你系统中已经安装 OpenWebmail 2.40 , 但尝试过并不需要.

用 Sun Cobalt restore CD 恢复系统后有两种方法安装 OpenWebmail v2.51

A. 用openwebmail 软件包直接安装

请安装 http://pkgmaster.com/packages/raq/550/  的安装包 Openwebmail v2.51 

B. 以源码方式手动安装，步骤如下

如果你是用以上安装包安装可直接跳过 (1)  (2)  (4)  (5) 四个安装步骤，如果你是源码手动安装请按步骤安装.

1) Upgrade MIME-Base64

cd /root wget http://cpan.org/modules/by-module/MIME/MIME-Base64-3.07.tar.gz tar zxf MIME-Base64-3.07.tar.gz cd MIME-Base64-3.07  perl Makefile.PL make make test make install

2) Get and install Open WebMail

  cd /root wget http://www.openwebmail.org/openwebmail/download/current/openwebmail-current.tar.gz mv openwebmail-current.tar.gz openwebmail-2.51.tar.gz mkdir owm cd owm tar zxf ../openwebmail-2.51.tar.gz cd /home mv openwebmail __old_openwebmail mkdir openwebmail cd openwebmail cp -r /root/owm/* .

3) Configure authentication and permissions

cp /home/__old_openwebmail/cgi-bin/openwebmail/auth/auth_pam_cobalt.pl 
/home/openwebmail/cgi-bin/openwebmail/auth/.

If you’re missing the file, you can get the contents at auth_pam_cobalt.pl

经过安装测试下载回来的 auth_pam_cobalt.pl 是不能正常工作的，可以自建新文件 auth_pam_cobalt.pl 并把以下内容贴上

-------------------  以上 auth_pam_cobalt.pl 代码完结 ---------------------

设置 sessions 目录的权限为所有用户 0771

chown -R root.mail * 
chmod 0771 /home/openwebmail/cgi-bin/openwebmail/etc/sessions

4) Disable CGIWrap

cd cgi-bin/openwebmail

Edit .htaccess to contain:

AddHandler cgi-script .pl

5) Create missing config file

Edit /home/openwebmail/cgi-bin/openwebmail/etc/dbm.conf to contain:

dbm_ext                 .pag 
dbmopen_ext             none 
dbmopen_haslock         yes

6) Fix the main configuration file

cd /home/openwebmail/cgi-bin/openwebmail/etc 
mv openwebmail.conf openwebmail.conf.orig

Edit openwebmail.conf to contain:

# Open WebMail configuration file 

# # This file contains just the overrides from defaults/openwebmail.conf, 
# please make all changes to this file. 

# # This file sets options for all domains and all users. 
# To set options on per domain basis, please put them in sites.conf/domainname 
# To set options on per user basis, please put them in users.conf/username 

# # Please refer to openwebmail.conf.help for the description of each 
option  domainnames             
auto domainnames_override    yes

spellcheck              /usr/bin/ispell

7) Run the init script

 /home/openwebmail/cgi-bin/openwebmail/openwebmail-tool.pl --init
