• BlackBerry® Enterprise Server for Microsoft® Exchange version 2.1 to 5.0

Administrators can configure the BlackBerry Enterprise Server to delay mail processing in order to allow time for anti-virus or anti-spam software to scan messages.

Warning: The following procedure involves modifying the computer registry.  This can cause substantial damage to the Windows® operating system.  Document and back up the registry entries prior to implementing any changes.

To delay mail processing, complete the following steps:

1. In the Registry Editor, go to one of the following locations: 
   
   For BlackBerry Enterprise Server version 2.1 and earlier:
   
   HKEY_LOCAL_MACHINESoftwareResearch In MotionBlackBerryServer
   
   For BlackBerry Enterprise Server version 3.5 to 3.6:
   
   HKEY_LOCAL_MACHINESoftwareResearch In MotionBlackBerryServers<BlackBerry_Enterprise_Server_name>
   
   For BlackBerry Enterprise Server version 4.0 to 5.0:
   
   HKEY_LOCAL_MACHINESOFTWAREResearch In MotionBlackBerry Enterprise ServerAgents
   
2. If the ProcessMailDelay registry entry already exists, change the Value data field to the number of seconds you would like mail processing to be delayed. If the ProcessMailDelay registry entry does not exist, create a registry entry with the following values:  
   
   

   Name	Type	Value
   ProcessMailDelay	DWORD	This value specifies the number of seconds to delay mail processing. For example, a value of 5 delays mail processing for 5 seconds.

    
3. Restart the BlackBerry Dispatcher and BlackBerry Controller.

Important: Restarting certain BlackBerry Enterprise Server services will delay message delivery to BlackBerry devices. See article KB04789 for more information.
