XADM: Rules Are Not Applied to SMTP Messages Received as [cc]

• Microsoft Exchange Server, version 5.5
• Microsoft Outlook Windows NT client, versions 8.03 and 8.5
• Microsoft Outlook Windows 95/98 client, versions 8.03 and 8.5
• Microsoft Exchange Windows NT client, versions 4.0 and 5.0
• Microsoft Exchange Windows 95/98 client, versions 4.0 and 5.0

SYMPTOMS

When you receive a Simple Mail Transfer Protocol (SMTP) message with your address specified in the CC field, rules may not be applied as follows:

Exchange Client 4.0 and 5.0, and Outlook 97

• If the "Copied (Cc) to me" check box is selected, rules are not applied.
• If the "Sent directly to me" check box is selected, rules are applied.

Outlook 98

• If the "Where my name is in the Cc box" check box is selected, rules are not applied.
• If the "Sent directly to me" check box is selected, rules are applied.

CAUSE

This behavior occurs because the Internet Mail Service gets the recipient's information through the "RCPT TO:" command, and holds the recipient's information as P1 information. From the P1 information, the recipient list is generated internally, and then converted to the MAPI properties.

The To, Cc, and Bcc fields are P2 properties, and in the case of incoming mail, the Internet Mail Service does not parse these to figure out who is in the To, Cc, or Bcc fields, and mark them in the recipient list that was created at the P1 level.

In the case of the "Copied (Cc) to me" or "Where my name is in the Cc box" rules, the property PR_RECIPIENT_TYPE determines whether the recipient was specified in the To or Cc field in the message. Because the Internet Mail Service always sets PR_RECIPINET_TYPE to a value for To, the rule for messages received as Cc doesn't work correctly.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:

MORE INFORMATION

This hotfix sets the correct value for PR_RECIPIENT_TYPE property of an outbound message. By sending this message to the Internet in Transport Neutral Encapsulation Format (TNEF), the correct value will be set for PR_RECIPIENT_TYPE of the inbound message, and the rule will work correctly. Therefore, in order for an SMTP message with your name specified as in the Cc field to work correctly using this hotfix, the following conditions must be met:

• The message you want to apply the rules to should be sent from the server to which this hotfix is applied.

  The hotfix must also be applied to the Internet Mail Service server to send the message to the Internet. The number of modules which you must apply is different whether the Internet Mail Service is installed or not.
