I'd like to set up an internal e-mail address to automatically redirect all received e-mails to an external address using Exchange 2007. There are articles describing how to set up a forwarding rule on the server to forward e-mails, but I am assuming that this will work as a client forward, e.g. that the recipient of the e-mail will see the internal e-mail account as the sender, not the original sender of the e-mail?
Is it possible to set up a similar rule that redirects e-mails instead? I know that using Outlook you can make this distinction when using Outlook rules, but these will not redirect/forward e-mails to external addresses.
EDIT: Another option would be to only enable automatic forwarding for a single Exchange account, but from the google results I am getting neither options seems possible.
