Note: Setting this variable requires a restart of HTTP task
Applies to Lotus iNotes clients. Use this setting to enable the Mail - Message Marking user preference in iNotes, so that users can set a user preference to display icons in Mail views that indicate whether they were the only recipient, or one of many. For mail sent to the user's Notes-style address, these icons indicate whether the user's name is the only name in the To field, whether it is listed with others in the To field, or whether it is in the cc field. 0 - (default) iNotes users will not be able to set message marking preferences, nor will they be able to modify message marking preferences set in the Notes client. 1 - iNotes users will be able to set message marking preferences, and will they be able to modify message marking preferences set in the Notes client. If users previously set this feature in the IBM Lotus Notes client, the icons also display in iNotes whether this setting is enabled or not. However, this setting must be enabled to allow users to set or modify this setting from iNotes user preferences. Note: Previous versions of iNotes were called Domino Web Access.
