Filtering to, CC, BCC fields for a particular string and performing an

[Macinslaw]

I need to be able to filter out anything sent to our old domain, not to block, but to basically change the subject line, or alter the delivery location based upon whether the email was sent to our old or new domin. I figure that Exchange is no the right software, but I figured some one here may have had to perform the same function and old.

Thanks.

What are you trying to achieve specifically and maybe we can provide a solution.

Here's what we are looking to do:

We changed our company name. We do not want to shut down the old email addresses until we know that most of our clients are using the new email addresses with the new domain names. So, we would like to find some way of filtering all email that comes in under the old domain name to be allowed through, but tagged in the subject line, "Still using old email addess". That is our goal.

Right - this isn't what you want but it is the most used:

mac@olddomain.com is the format at the moment. olddomain.com has an MX10 pointing at the public IP of the Exchange server.

Buy newdomain.com

Change the SMTP addresses for all within AD to mac@newdomain.com etc using a recipient update policy.

Change the bridgehead if you need to so that it specifies newdomain.com if you can't do the AD change.

Point newdomain.com at the same public IP address.

Use whatever email logging software you have on the bridgehead to report on how many are coming in to the old address.
