How to Modify Global Settings in Exchange System Manager

This article describes how to modify global (organization-wide) settings in Exchange System Manager. The following most common administrative tasks are discussed:

• Set delivery restrictions.
• Create a message filter rule.
• Permit or prevent out-of-office replies to the Internet.
• Permit or prevent Rich Text formatting in messages.
• Permit or prevent sending display names to the Internet.

Set Delivery Restrictions

To set delivery restrictions for the whole organization:

1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. In the left pane, expand the Global Settings container, right-click Message Delivery, and then click Properties.
3. Click the Defaults tab, and then modify the settings.
   • To limit the size of outgoing messages, click Maximum (KB) under Outgoing message size, and then type a value in the box. To remove all limitations on the size of outgoing messages, click No limit under Outgoing message size.
   • To limit the size of incoming messages, click Maximum (KB) under Incoming message size, and then type a value in the box. To remove all limitations on the size of incoming messages, click No limit under Incoming message size.
   • To limit the number of recipients for a single message, click Maximum (recipients) under Recipient limits, and then type a value in the box. To remove all limitations on the number of recipients, click No limit under Recipient limits.
4. Click OK.

Create a Message Filter Rule

Message filtering applies to all Internet Protocol (IP) addresses that are configured on every Simple Mail Transfer Protocol (SMTP) virtual server in your organization. You can have more than one IP address associated with an SMTP virtual server. Message filtering can be enabled for some IP addresses and not enabled for others.

• Connection Filtering
  
  Use Connection Filtering to block messages that are received from specific SMTP servers.
• Recipient Filtering
  
  Use Recipient Filtering to block messages that are sent to particular recipient addresses.
• Sender Filtering
  
  Use Sender Filtering to block messages that are sent by specific users. This may be helpful when you want to block unsolicited commercial e-mail from being delivered to users in your organization.

To create a message filtering rule for the whole organization:

1. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
2. Expand the Global Settings container in the left pane, right-click Message Delivery, and then click Properties.
3. Click one of the following tabs, depending on the type of filtering that you want to configure:
   • Connection Filtering
   • Recipient Filtering
   • Sender Filtering
4. Click Add, type the appropriate parameter that you want to configure, and then click OK.
   
   For more information about how to configure each type of message filtering, click Help on the tab for the type of message filtering that you want to configure.
5. Repeat step 4 for each message filtering rule that you want to create.
6. If you want the filtered messages to be moved to the Exchsrvr\Mailroot\Server_Name\Filter folder (where Server_Name is the SMTP virtual server that the message is filtered for), click to select the Archive filtered messages check box on the Sender Filtering tab.
   
   This folder is automatically created when the first message is filtered. If the Archive filtered messages check box is not selected, the filtered messages are deleted instead of being moved to this folder.

Note After you create a message filtering rule for the whole organization, you must enable message filtering on an SMTP virtual server. If you create a message filtering rule, and a message that meets the criteria that you specified is sent to the server, the message is not filtered unless message filtering has been enabled for a particular IP address that is bound to an SMTP virtual server.
