MDaemon Messaging Server[1] は、Texas州に位置するAlt-N Technologies社 [2]が開発した、Windowsベースのメール・グループウェアサーバーソフトウェアである。

MDaemonは、標準搭載された、ヒューリスティック分析やベイジアン解析を使ったスパムフィルタ、SSL/TLSでの暗号化、パブリックフォルダや共有フォルダ、メーリングリスト、ウェブベースのメールクライアント(WorldClient)、グループウェアデータ(予定表、連絡先、仕事とメモ)の共有、ActiveSyncを介したover-the-air によるモバイル端末とのデータ同期、BlackBerry Internet Service、更に追加オプションとしてBlackBerry Enterprise Server (BES) プラグイン[1]といった機能を搭載している。




MDaemonは、1990年の半ば、Arvel Hathcockが開発を始めた。Hathcockは14歳で父親に買ってもらったTRS-80モデルMC-10で開発を始め、複数の企業向けに掲示板ソフトを開発した後、Mailing List Systems Corporationへ所属した。Hathcockは当時のメールソフトウェアにかかるコストにフラストレーションを感じ、1996年、自分でメールシステムを開発しようと決意した。1996年、Alt-N Technologiesを設立し、Hathcockの商用メールサーバー、 MDaemon[3]が生まれた。


WorldClient (ウェブベースのメールクライアント)[編集]

MDaemonに搭載されているウェブベースのメールクライアント (WorldClient) を使うと、ブラウザからメールや予定表、連絡先、ドキュメント、仕事、メモへアクセスする事ができる。ドキュメントはメッセージへ添付したり、ドラッグ&ドロップで共有フォルダへ追加したりする事ができる。パブリックフォルダや共有フォルダを共有する際には個別のアクセス権限が設定できる。サイドバーに組み込まれたチャット機能は、他のMDaemonユーザーとのチャット[4]に利用できる。

リモート管理 (WebAdmin)[編集]

リモート管理(WebAdmin) はMDaemonの設定を行うために搭載されている機能である。ウェブベースのリモート管理ツールを使うと、アカウント管理、セキュリティ管理、モバイル管理、ログの確認、といった、MDaemonのほとんどの設定[5]にアクセスできる。

プライベート・インスタント・メッセージ (ComAgent)[編集]

標準搭載された、プライベート・インスタント・メッセージ用クライアント(ComAgent)により、 [6]グループチャットや連絡先一覧、ファイル共有、メール通知、アドレス帳の自動同期などの機能を使う事ができる。
