Forward email while changing the sender's address?

I have a quick question with regards to email forwarding within Exchange Server 2003.  I know how to forward emails using exchange contacts...etc, but I am not positive if it is possible to forward an email from an external account to an Exchange server account, which then forwards the email to a different external account (a client's external email account).

I know spam can work this way which is why I am hesitant to reasearch this further, but one of our clients has requested this service if possible.  

Goal: sends an email to then forwards the email, while replacing the from address ( with, to our client's email account  

Is this possible and if so is there an easy/secure way to implement it.

If this is a dumb request, please just let me know and I will consider the matter closed.

Thanks in advance!

You can achive this, But its restricted by default in Exchange server 2003.
You will have to enable this from Global Settings in Exchange System Manager - Expand Global Settings - Highlight Internet Message formats - Pull up the properties of your domain in the right side.
Go to "Advanced" tab, select "Allow automatic forwarding" checkbox. This would allow you to create rules to forward mails to external addresses.

Thank you for your replay Amit.

I am going to test out the configuration you mentioned, but I want to try and keep the rest of our users from having this ability built-in to Outlook.  Do you know of a way to deny users the ability to create forwarding rules from group policy?  I loaded the Outlook 2003 ADM files, but I was not able to locate a policy for rule creation.

Again, thank you for your help.

I am not aware of using Group Policies to achive this. If you will enable it from Global Settings as metioned earlier, You will have to restart your SMTP and Routing Engine service once. and then, every user in your organization will be able to forward mails to external users.
