[root@dns mail]# /var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init
Please change '/var/www/cgi-bin/openwebmail/etc/dbm.conf' from
dbm_ext .db
dbmopen_ext .db
dbmopen_haslock no
to
dbm_ext .pag
dbmopen_ext none

And execute '/var/www/cgi-bin/openwebmail/openwebmail-tool.pl --init' again!
ps: If you are running openwebmail in persistent mode,
don't forget to 'touch openwebmail*.pl', so speedycgi
will reload all scripts, modules and conf files in --init.

Welcome to the OpenWebMail!
This program is going to send a short message back to the developer,
so we could have the idea that who is installing and how many sites are
using this software, the content to be sent is:
OS: Linux 2.6.32-358.23.2.el6.x86_64 x86_64
Perl: 5.010001
WebMail: OpenWebMail 2.53 20080123
Send the site report?(Y/n) n
Thank you.
5.重啟動apache
service httpd restart
6.測試登入
http://ip/webmail 或 http://domain/webmail
登入後發現錯誤訊息..
/var/log/openwebmail.log! (Permission denied)
解決方式：
[root@dns log]# touch /var/log/openwebmail.log
[root@dns log]# chcon -u system_u /var/log/openwebmail.log
[root@dns log]# chcon -t httpd_sys_script_rw_t /var/log/openwebmail.log
[root@dns log]# chcon -t httpd_unconfined_script_exec_t /var/www/cgi-bin/openwebmail/openwebmail*
說明：
touch /var/log/openwebmail.log <==這是產生一個log檔
chcon -u system_u /var/log/openwebmail.log <==這是修改檔案使用者權限
chcon -t httpd_sys_script_rw_t /var/log/openwebmail.log <==這是修改寫入權限
chcon -t httpd_unconfined_script_exec_t /var/www/cgi-bin/openwebmail/openwebmail* <==這是修改檔案由什麼套件專用
這些都是因為SELinux造成的，原本檔案、目錄權限只有使用檔案前面那串（rwxrwxrwx），在使用SELinux後，會多出一種管理context type，context type會限制該目錄、檔案的使用原則，
所以，在使用有安裝SELinux時，常常會出現apach、ftp明明 都設定好了，卻還是不能使用，多半出問題，都是SELinux在做怪。

7.修改/var/www/cgi-bin/openwebmail/etc/openwebmail.conf
#default_language en
default_language zh_TW.Big5
#default_iconset Cool3D.English
default_iconset Cool3D.Chinese.Traditional
#default_fontsize 10pt
default_fontsize 12pt
#default_dateformat mm/dd/yyyy
default_dateformat yyyy/mm/dd
#default_hourformat 12
default_hourformat 24
#domainnames auto
domainnames 你的domain
8.設定郵件過濾規則修改/var/www/cgi-bin/openwebmail/etc/filter.book 在最後面加上
01@@@subject@@@include@@@game@@@move@@@mail-trash@@@1@@@big5
規則說明：
01:郵件規則優先順序.
subject：郵件規則過濾條件在郵件主旨中生效.
include：郵件規則過濾條件包含或不包含下列設定的關鍵字
game：郵件規則的關鍵字.
move：將垃圾信件搬移或複製的目的信匣.
mail-trash：設定垃圾信件的目的信匣.
1：設定的郵件規則過濾條件生效.
big5：設定郵件規則的語系.
其他錯誤解決方式：
問題1.使用帳號itest登入http://網域/webmail後發生下列錯誤：
無法建立 /var/www/cgi-bin/openwebmail/etc/sessions/itest*網域-session-0.817896068652288! (Invalid argument)
解決方式：
依據文件/var/www/cgi-bin/openwebmail/etc/openwebmail.conf.help說明
ow_sessionsdir
-----------------------------------------------------------------------
the directory for openwebmail temporary session files and attachments
currently used by each session.
ps: This directory would become very large if you have many concurrent
webmail users. So please put it in a partition with enough space.
ps: The permission for ow_usersdir and ow_sessionsdir directories should be
mode: 750
owner: the user that OWM script will be running as (root in many cases)
group: mail
執行 [root@dns sessions]# chmod 775 /var/www/cgi-bin/openwebmail/etc/sessions
備註： openwebmail 2.53不支援 Maildir
若etc/postfix/main.cf 設定使用home_mailbox = Maildir/，
而非home_mailbox = Mailbox則會收不到信件，需特別注意
