Server Monitoring

Have got a queue of about hundred mails awaiting delivery.This could be as a result of very big file attchments.Please help I need a tool to monitor user activity or to filter mails according to a set criteria such that at most I have about fifty mails awaiting delivery at a time.

To monitor “mail.box” and notify administrator if there are more than 50 documents in the mails view, you can use Larm-O-Matic application from our company. With it you can also choose to run an agent instead of notifying administrator.
