This may sound like a dumb question, but it's the first time i've encountered this. I have a new client who is using tds for their ISP. They have a domain name setup that is autoforwarding any email from that domain name to a tds.net email address. They now want to setup their own Small Business server and host the email from the exchange server portion of SBS. I believe that i need to have the ISP (TDS) setup an MX record change to point to the public (outside) ip address of the sbs server-- is that correct? or does the domain name hosting company have to do that?
