Storage Quota Warning messages that are sent to the user will bypass the restriction if a user configures an auto-forward rule or an auto-reply rule to send e-mail messages to a restricted distribution group

This article has been archived. It is offered "as is" and will no longer be updated.
Consider the following scenario:
  • In a Microsoft Exchange Server 2003 environment, the user configures an auto-forward rule or an auto-reply rule to send e-mail messages to a restricted distribution group (DG).
  • The user does not have permission to send e-mail messages to that restricted DG.

In this scenario, any Storage Quota Warning messages sent to the user will bypass this restriction. Then the Storage Quota Warning messages will be delivered to the restricted DG.
Storage Quota Warnings are currently not treated as Delivery Status Notification messages. Instead they are treated as System Messages. This behavior occurs because all the message attributes are copied from the original message to the forward or reply message.This includes the PR_CONTENT_IDENTIFIER. The PR_CONTENT_IDENTIFIER identifies the message as an ExSysMessage type (System Message) when the rule is proceeding with the message. In the Categorizer component, where restrictions are checked, System Messages automatically bypass any restriction check. Therefore the Storage Quota Warning message is delivered to the DG.
