advice for mail relay service

My company is currently running Exchange Server 2000, and while it wouldn't be my first choice, it works for what we need. However, it does have some clunky ways of doing things, and has caused us go looking for a solution.

Some of our employees have an email address in this domain (ie. and want the mail the comes to that address forwarded to another address outside our domain. Exchange does this with ease. The problem comes when that same employee has a second address at our company that may relate to his/her position (ie. but wants that address to forward to the same outside domain address as Exchange can not do this well at all.

The best solution I have come up with is to put a linux box on the backbone with a mail relay that has a simple, line-by-line list of forwarding rules, and then once the mail gets filtered (and the "To:" field modified if need be), it gets passed onto the Exchange server to be sent out. So my question is, what program would best meet this need? I'm more comfortable in a Linux enviroment, but if there is a windows program that can do this well too, let me know.

I'd honestly suggest replacing the MS Exchange server with a sendmail/linux server
It can provide all that the exchange server does, without the limitations.
I have done this at our company, and it handles fairly complex redirects, especially for the road warriors who have accts in two domains, as well as their personal email accounts redirecting via the server.

So I could retire gracefully, I set up webmin on the server, so as much of the admin (new users, rules, etc) could be done by office staff with a browser, and I'd only have to go in 'occasionally. As it turns out, it's so simple they haven't called yet.

Works even better if you use ximian evolution as the desktop mail client .. integrates beautifully with the linux/sendmail/ldap servers to provide an outlook-like environment, complete with corporate (shared) address book
