I think Microsoft Outlook on Office has a feature that does something like that. I don't know too much about working with MSN. I have a network that I'm a part of so that's how my E-mail is handled. Outlook has an Out of Office Reply function. It also has a Rules Wizard for how mail is handled. I think that that is how you would go about figuring out. Also, you could do it the hard way and cc like mike said. You'ld probably just want to add it to your address book if you were to do it that way. If you use Outlook, then there is probably a way. If you are just using MSN, then you probably won't be able to. Not to sure though.
the day we stop thinking is the day we start sinking
