DiskQuotaErrMaker

Last updated at Posted at 2024-12-26

  • 特定のメールボックスを容量超過させる必要があり作成したものです。

  • 指定したメールアドレス宛に10MBの添付ファイルを指定回数分送信してDiskQuotaErrを発生させます。

  • メールソフトで行おうと思いましたが10GBytes送る場合は1000回メールの操作をする必要が有り諦めました。
    (1GBのファイルが送れれば良いがSMTPはそんな大サイズは送れない)

  • 右下のボタンで稼働中と停止中の切り替えが可能。

  • 宛先を間違えると大変な事になりますので使用は注意して下さい。

メークする前にソースヘッダ部のconst値を変えて下さい。
fsutil.exe等で10MB程度のファイルを作り　AttPath=@"C:\10MB";　に指定。
