Installing OpenWebmail 2.51
From CobaltFAQs
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
——————– 以下为 auth_pam_cobalt.pl 的内容 ——————-

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 auth_module auth_pam_cobalt.pl mailspooldir /var/spool/mail ow_cgidir /home/openwebmail/cgi-bin/openwebmail ow_cgiurl /openwebmail-cgi ow_htmldir /home/openwebmail/data/openwebmail ow_htmlurl /openwebmail logfile /var/log/openwebmail.log enable_viruscheck no enable_spamcheck no enable_learnspam no default_iconset Default default_fscharset none <default_signature> </default_signature> <page_footer> </page_footer> use_homedirspools yes homedirspoolname mbox spellcheck /usr/bin/ispell default_language en timeoffset auto
7) Run the init script
/home/openwebmail/cgi-bin/openwebmail/openwebmail-tool.pl --init
