Identifying busy distribution lists helps administrators perform expansion server load balancing easily, as they would be in a much better position to judge which free server a busy distribution list should be moved to.
One can filter out traffic summary for any specified time and even drill it down to hourly traffic rate. The reports also provide you the flexibility of extracting distribution list traffic summary for specified intervals, which is an important aspect that makes post-mortem of any unusual spikes in traffic easy.
Some viruses, especially spam malware or Trojans, get hold of a user´s GAL (Global Address List) and shoot out a barrage of emails to every email address contained in it. Therefore, it is a good practice to monitor the number of mails a user sends to a distribution list, to look for unusual piques, and to prevent email onslaughts well ahead of time.
And again, with the available filters, it becomes easy to identify potential threats and take evasive actions.
