Message-ID in outbound header

Is there any way to remove/block/alter this in outbound mail for
Exchange 2003 to avoid showing the internal server's host name to the
world?

Hi Nate:You could change the FQDN of the default SMTP VS.

Hi Nate:

You could change the FQDN of the default SMTP VS. There seems to be some
different opinions on doing this. I personally have done it to resolve an
e-mail delivery issue because certain recipient systems rejected the message
since the internal FQDN did not match up with the external FQDN. Based on
that particular setup, I did not really have any other option.

For your situation, you probably do not want to change it since it is not
causing any issues as is. See "Myth 3b: Modifying The FQDN of the SMTP
Virtual Server" at http://msexchangeteam.com/archive/2005/02/25/380481.aspx.

Appreciate the response but the SMTP VS FQDN does not seem to affect
the Message-ID portion of the header.  It does affect a different
portion of the mail header but unfortunately not the Message-ID
section.  I know Exchange 2007 has the ability to block this portion
of the header but I do not see any easy solution for 2003.

Just noticed that even your link states modifying the SMTP VS FQDN
will not affect the Message-ID.  :o)

Duh!

Duh! My bad. I am not aware of any way to modify that part of the header.
That's really getting down to a lower level of Exchange operation, so I am
not sure if there is a supported interface to change that.

If the server's name is not resolvable in your External DNS, and your
internal network is protected by adequate security, there is no danger
of the machine being abused. If your preimeter security is breached it
will not take much longer than 30 seconds to find the server -- but at
that point you will have much bigger problems to deal with.

Do you know what can happen in 30 seconds?
