(2)宛先「ddd@ddd.com」、「eee@eee.com」および「fff@fff.com」のユーザーが組織Aに所属しており、宛先「ggg@ggg.com」および「hhh@hhh.com」が組織Aとは別の組織Bに所属しており、メールの内容を組織Aおよび組織B内で共有してほしい。
上記の実施形態1では、メールクライアント1のメールデータ生成部53が、BCC宛先を通知する旨の設定を受け付けた送信宛先については、当該送信宛先を送信先としたエンベロープ情報および当該BCC宛先を含むヘッダ情報を含むメールデータを生成し、BCC宛先を通知する旨の設定を受け付けない送信宛先については、当該送信宛先を送信先としたエンベロープ情報および当該BCC宛先を含まないヘッダ情報を含むメールデータを生成した。これに対して実施形態1の変形例では、メールクライアント1のメールデータ生成部53が、送信宛先毎に複数のメールデータを生成するのではなく、1つのメールデータを生成して、当該1つのメールデータをメールサーバー2Aに送信する。メールサーバー2Aでは、受信した1つのメールデータに含まれる情報を解析して、送信宛先毎に複数のメールデータを生成して、各メールデータをメールサーバーに送信する。
実施形態2にかかるメールクライアント1では、受付部52が、複数のBCC宛先を含む送信宛先を受け付けた場合に、当該各BCC宛先が所属するグループを示すグループ属性の設定を受け付ける。
上記の実施形態2では、メールクライアント1のメールデータ生成部53が、グループ属性の設定を受け付けたBCC宛先については、当該BCC宛先を送信先としたエンベロープ情報および当該BCC宛先と同じグループに所属する他のBCC宛先を含むヘッダ情報を含むメールデータを生成し、グループ属性の設定を受け付けないBCC宛先については、当該BCC宛先を送信先としたエンベロープ情報および他のBCC宛先を含まないヘッダ情報を含むメールデータを生成した。これに対して実施形態2の変形例では、メールクライアント1のメールデータ生成部53が、送信宛先毎に複数のメールデータを生成するのではなく、1つのメールデータを生成して、当該1つのメールデータをメールサーバー2Aに送信する。メールサーバー2Aでは、受信した1つのメールデータに含まれる情報を解析して、送信宛先毎に複数のメールデータを生成して、各メールデータをメールサーバーに送信する。
上記実施の形態で説明したメールデータ送信プログラム(通信制御プログラム)をコンピューター読み取り可能な非一時的な記録媒体、例えば、ハードディスク、CD-ROM、DVD-ROM、半導体メモリーなどに記録されたものとしてもよい。この場合、当該メールデータ送信プログラムを記録したコンピューター読み取り可能な非一時的な記録媒体が、本発明の一実施形態となる。
