You can create your own personalized Java indicators.

Management processes for Java user-defined indicators are the same as those for system indicators.

You can also import a ready-to-use Java user-defined indicator from the Exchange folder in the DQ Repository tree view. This Java user-defined indicator connects to the mail server and checks if the email exists.
