刚写了一篇长篇大论，结果没有上传上去，后悔没有保存，所以第二次些没有什么激情了，是这样的，以前曾问过有关在rh8平台上架设sendmail＋openwebmail的问题，后来索性自己找资料来配，现在终于功德圆满。
全过程实录：
1、rh8的安装和sendmail的配置可以看看以前peng和心余的文章。这里不赘述。
2、 http://openwebmail.com/openwebmail/download/redhat/ 的rpm目录下的全部东西，主要有：
perl-CGI-SpeedyCGI-2.21-RH80.i386.rpm
openwebmail-2.10-1.release.i386.rpm
perl-Compress-Zlib-1.21-RH80.i386.rpm
openwebmail-2.10-20030712.i386.rpm
perl-suidperl-5.8.0-55.i386.rpm
perl-Text-Iconv-1.2-RH80.i386.rpm
perl-CGI-2.81-55.i386.rpm

分别安装，openwebmail需要的东西在这些包里都有了。
安装完成后查看00－howto.txt文件，全文如下：
How to install Open Webmail on Red Hat Linux 8.0
=================================================
By Thomas Chung (tchung AT openwebmail.org)
Last Updated 2003-06-14
************ Special Message from the Developer *******************
There is a bug in tell() in perl 5.8 which would return wrong offset
if it is called after open(F, ">>file");
This is a serious bug which may corrup the folder file in some case.
If you are using perl 5.8 (eg: RedHat 8.0 uses perl 5.8 by default)
a. upgrade your openwebmail to the latest version (1.81 or higher)
as soon as possible
b. try to find a bug fix for your perl since other applications written
by perl may operate inproperly due to this bug
(by running "openwebmail-tool.pl --init")
**********************************************************************
pre-requisites: httpd-2.0.40-8.i386.rpm and httpd service is running
sendmail-8.12.5-7.i386.rpm and sendmail service is running
1. install all perl rpm packages if you haven't installed yet.
2. install the latest openwebmail rpm build from daily build directory
3. initialize openwebmail database using openwebmail-tool.pl
cd /var/www/cgi-bin/openwebmail
./openwebmail-tool.pl --init
3.1) change the following 3 options in openwebmail.conf
from
dbm_ext .db
dbmopen_ext none
dbmopen_haslock no
to
dbm_ext .db
dbmopen_ext %dbm_ext%
dbmopen_haslock yes
(UPDATE: if you don't have following file, skip step 4.2 and 4.3)
3.2) modify /usr/lib/perl5/5.8.0/i386-linux-thread-multi/DB_File.pm by adding
$arg[3] = 0666 unless defined $arg[3];
before the following text (line 250)
# make recno in Berkeley DB version 2 work like recno in version 1
3.3) execute './openwebmail-tool.pl --init' again
You won't see the same suggestion for changes or modification.
4. create a user account if you haven't created one yet
5. login to openwebmail using a user account
http://localhost.localdomain/cgi-bin/openwebmail/openwebmail.pl
For Virtual Hosting Domains
===========================
If you are hosting mutiple domains with virtualHost directive,
add following lines in httpd.conf to access openwebmail login screen for each domain.
ex) http://domain.com/webmail
# Open Webmail ScriptAlias, Alias
ScriptAlias /webmail "/var/www/cgi-bin/openwebmail/openwebmail.pl"
Don't forget to restart httpd.
现在测试以下您的openwebmail，一切ok。
其实按照帮助文档，应该都可以配出来的。（linux知识宝库）
