Removing Information from Message Headers in Exchange 2007 Welcome to the March 2008 edition of the MSExchange.org newsletter! Since December 2006 where Exchange 2007 released to manufacturing (RTM) up until now I have seen several questions from Exchange admins around the world revolving around whether it is possible to hide the internal server names and IP addresses (that is the routing headers) of their Exchange 2007 Transport servers from the message header of a message leaving the Exchange 2007 organization. So the first question that probably comes to mind is if this at all possible? The answer is yes. Then how is this accomplished, then? Well it is actually pretty straightforward if you know what mechanism to use. Exchange 2007 includes a mechanism called header firewall, which by default removes custom X-headers from a message header of both inbound as well as outbound messages. X-headers are special fields inserted into the message header by Exchange 2007 Hub and Edge Transport servers. Things such as Exchange 2007 transport rules, anti-spam filtering agents etc. inserts X-headers into the message header of the messages travelling through the Exchange 2007 Transport servers in the organization. Because the inserted X-headers could contain sensitive information they are removed from both inbound messages that come from untrusted sources (primarily to prevent spoofing) as well as outbound messages destined for untrusted destinations (as this could otherwise pose a potential security risk) by the aforementioned header firewall. Guess what? Yes correct! The header firewall can also be used to remove standard routing headers for inbound and outbound messages. This is done on the connector level. This means that if you want to remove the routing header of messages leaving the organization, you would need to do so by setting the Ms-Exch-Send-Headers-Routing permission to false on the send connector used to route messages to the Internet. Note: By default, the Ms-Exch-Send-Headers-Routing permission is assigned to all send connector types except custom send connectors. To see the Ms-Exch-Send-Headers-Routing permission assigned to a send connector type: Get-ADPermission - Identity "Name of Send Connector" | FL Figure: ADPermissions set on a Send Connector For more information revolving around the header firewall mechanism in Exchange 2007, see the following section in the Exchange 2007 TechNet documentation: http://technet.microsoft.com/en-us/library/bb232136.aspx.

Ask Henrik Walther a question QUESTION: I seem to have a dilemma. I have a queue that has a message in it. The queue is in retry state, I try to delete the message but everything is grayed out when I highlight the message and right click on it, so I am unable to delete the message stuck in the queue. Any suggestions? ANSWER: The Exchange Management Shell may very well come to the rescue here. Using the Remove-Message cmdlet, you can among many other things delete single messages from a queue. For instance, to delete a message from a particular sender, you would use a cmdlet similar to the one below: Remove-Message -Filter {FromAddress -eq "Name_of_Sender@msexchangelab.org"} -withNDR $false If you, for example after a spam attack, rather want to delete all messages with a specific subject, you could instead use: Remove-message -filter {Subject -eq "Bad Mail Subject"} -WithNDR $false The -WithNDR $false parameter is used to specify whether a non-delivery report (NDR) should be returned to the sender of a message(s). By default this parameter is set to true, which is why we specify it as we don't want to send NDRs to what is probably spoofed domains anyway. To read more about the parameters available with the Remove-Message cmdlet, see: http://technet.microsoft.com/en-us/library/aa996371(EXCHG.80).aspx Archiving and The Federal Rules of Civil Procedure: Understanding the Issues The Federal Rules of Civil Procedure (FRCP) affects every organization involved in a federal legal matter.
