所需套件
openwebmail libcompress-zlib-perl

建議安裝套件
apache-ssl

微調 OpenWebmail
OpenWebmail 的設定檔位於 /etc/openwebmail/openwebmail.conf，建議修改其中的 domainnames 及 default_signature 區段：

（上略）
domainnames virtual.com


--
Open WebMail Project (http://openwebmail.org)
Debian Project (http://www.debian.org)

（下略）


修改 /etc/apache/httpd.conf，讓 Apache 不會傳送 Default Charset 資訊給 Client：

（上略）
# Default charset to iso-8859-1 (http://www.apache.org/info/css-security/).

AddDefaultCharset off
（下略）


在 Apache 上設定 Virtual Hosts
在安裝好 OpenWebmail 之後，直接以 Web Browser 連上 http://localhost/openwebmail/ 即可進入 Open Web Mail 畫面，但這個網址可不好記！所以我們可以使用 Apache 的 Name-based Virtual Host 功能，讓使用 www.domain.com 時可以連接上一般的 Web 畫面，但使用 mail.domain.com 時可以進入 Open Web Mail 畫面。方法是修改 /etc/apache/httpd.conf 如下：

（上略）
### Section 3: Virtual Hosts
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them.
# Please see the documentation at
# for further details before you try to setup virtual hosts.
# You may use the command line option '-S' to verify your virtual host
# configuration.

在 Apache 上設定 Virtual Hosts over SSL
方法也是類似，修改 /etc/apache-ssl/httpd.conf 如下：

（上略）
