Set the Message Processing Delay

A chat community attacker can send a continuous stream of short messages to users that causes the recipients' screens to scroll so quickly that the screen is unreadable. You can control this type of attack by applying a delay to user connections. A delay is the period of time, measured in seconds, that the server waits before processing the next message from a client.

To delay the processing of messages from a user class:

1. Start System Manager
   On the Start menu, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Create a user class for the chat community where you want to set the message processing delay, or select an existing user class and modify it.
3. Navigate to the Classes folder.

   Chat Communities

   1. Chat_community_name
   2. Classes
4. Right-click Classes, and then click Properties.
5. Click the Settings tab.
6. In Message processing delay (seconds), type a delay period length. The chat server waits this period of time between each message from a client who is a member of the user class.

7. Note   The number you type in this field can range from 0 to 10 seconds.
