PATROL for Microsoft Exchange Servers provides application classes that monitor and manage SMTP, X-400, and MTA queues. 

Within each queue, PATROL monitors the number of messages, the age of the oldest message, and the rate of growth of the queue. 

PATROL for Microsoft Exchange Servers 2003 provides the following automated recovery actions that work with queues:

  • When the total number of messages in all the SMTP queues exceeds 1000, PATROL increases the throughput rate of the SMTP routing engine.
  • When there is abnormally high queue growth on an Exchange server, PATROL suspends any RoundTrip sessions and resumes the session when the queue growth returns to normal.
