Postfixadmin ( Web GUI 虛擬郵件伺服器架設)
Description :
Virtual Mail Server
        Virtual Mail Server 的優點為多網域使用同一台機器，它可讓一台伺服器不會單獨只服務一個 Domain 而造成浪費，四位之前有使用 vm-pop3 做過這樣的機智，但是因為缺乏好良好的 Web GUI 管理介面而讓系統管理者非常的辛苦，每次有要修改新增資料時就要勞駕系統管理者 Console 到 Server 裡慢慢修改，這真的粉辛苦ㄋㄟ。不過現在四位找到一個新的軟體 Postfixadmin ，這真是個好東西我們可透過它的 Web GUI 介面管理虛擬郵件主機，我們可以開新的網域及增加刪除使用者還可設定管理者，哈哈 ~ 如此一來我這個系統管理者只要負責架設及維護就好，這下可輕鬆了 ^^
       除了 squirrelmail 的 pulgin 套件採抓取自行安裝外，其餘所有軟體安裝皆採用 ports 安裝，軟體安裝前已先更新過 ports tree ，虛擬郵件主機的主機名稱( Host name )為：vm ，網域名稱( Domain name )為：ntut.idv.tw、Server IP 為：88.88.88.88 ，DNS 也已指定過 MX 到 88.88.88.88 這個 IP，Server 架設完成後，所有要在虛擬郵件主機上跑的 Domain name DNS 皆需要指定 MX 到 88.88.88.88 這個 IP。
