Currently if we want to generate a report like, which messages came on server with more than xx MB size with their details like sender id, recipient id, date, subject etc. then it is not possible to generate such report. There are only option to generate top 25 users by size etc. which does not fulfill the whole requirement as we want to generate the report for all users and not just top 25 users.
Further the Message Status Summary and Message Volume Summary reports which includes all users but they do not include details of message like sender id, recipient id, date, subject etc. It can only give total count of messages which is not useful as there is no way to know sender id, recipient id from those reports.
So there is a feature request to provide such options in Message Tracking Reports. This Enhancement Request is submitted for Domino V12.
