I have a scenario that we have a mail domain name register for but when the emails going outside, it is taking the internal mail server information including server name and internal IP address  in the header as well.

So how can we fix this issue.

    on exchange 2007 you can remove using this procedure :

    "How to remove Received headers in Exchange Server 2007"
    Exchange Server 2007 offers an easy way to accomplish this. If your transport server sends outbound email directly using DNS lookup, or delivers to a smarthost without authentication, simply remove the Ms-Exch-Send-Headers-Routing permission assigned to Anonymous Logon a well-known security principal that refers to anonymous users, as shown below:

    Get-SendConnector "Connector Name" | Remove-ADPermission -AccessRight ExtendedRight -ExtendedRights "ms-Exch-Send-Headers-Routing" -user "NT AUTHORITY\Anonymous Logon"

    I personally wouldn't have any concerns with that information on my headers. If someone gets in to a position where that information is of use, then you have much bigger problems. Having that information hidden will slow any attack down for 30 seconds, if the attacker is having a bad day.

    Removing the information though can stop Exchange from detecting a loop, and is therefore not recommended.
