The left pane displays the LISTSERV Maestro explorer tree, with the "Suppression List" node.
The pane on the right allows you to manage the addresses on the suppression list.
By default, the addresses are shown in ascending order. Click the "Address" column header to change the ordering.
To filter the subset of addresses shown, click the field just below the "Address" column header. This displays a popup dialog with the current filter settings of the suppression list. Select the desired filtering option and fill out any parameters. Click the [OK] button to apply the filter settings.
